What is an Analog to Digital Converter (ADC)?

An analog-to-digital converter is a device that is used to convert the continuous analog signals (voltage or current) into discrete digital numbers or digital data that various devices can process, like microcontrollers and ICs. 

In simple words, ADC takes analog signals from the atmosphere, like temperature, sound, or light, with the help of a sensor, and transforms them into a digital form. ADC is widely used in all electronics domains like communication systems, embedded systems and microcontrollers, automotive sensors, and IoT devices, etc.

Types of Analog to Digital Converters

1. Sigma Delta ADC

Sigma Delta ADC works well for low- to medium-speed applications and provides very high resolution with excellent noise performance. These are widely used in audio signal processing, precision measurement instruments, and digital audio converters.

2. Successive Approximation Register (SAR) ADC

This is the most common ADC type used in microcontrollers which offers a good balance of speed, resolution, and power efficiency. It is used in applications like data acquisition systems, industrial controls, and instrumentation.

3. Flash ADC

This is the fastest type of ADC. It uses a bank of comparators for instant conversion and is suitable for high-speed applications like digital oscilloscopes, radar systems, and RF signal sampling.

4. Dual Slope ADC

Dual slope ADCs are known for their high accuracy and noise rejection, but have relatively slow conversion speed. They are commonly used in digital multimeters and precision measurement devices.

5. Pipelined ADC

Pipelined ADC provides a good combination of high speed and medium-to-high resolution. They are often used in video, communications, and high-speed data acquisition systems.

6. Integration ADC

Integration ADC converts by integrating the input signal over a period. They are known for rejecting noise and line-frequency interference. They are used in low-speed, high-accuracy applications like digital voltmeters.

7.Time-Interleaved ADC

They use multiple ADC cores working in parallel to increase effective sampling rate and are suitable for very high-speed data converters in communications and test equipment. 

8. Counter Type ADC

These ADCs use a counter and a DAC to perform conversion. They are simple in design but have a slow speed. They are rarely used in modern applications due to speed limitations.

How Does an ADC Work?

1. An analog-to-digital converter (ADC) works by sampling a continuous analog signal at discrete time intervals.

2. It measures the amplitude of the input signal at each sampling point.

3. The continuous amplitude is then quantized into a finite number of levels based on the ADC’s resolution (e.g., 8-bit, 12-bit, 16-bit).

4. Each quantized level is assigned a unique binary code that represents the analog value digitally.

5. The sampling process must follow the Nyquist theorem to prevent signal aliasing.

6. An internal clock controls the sampling rate, defining how many samples per second the ADC takes.

7. The conversion process involves three steps: sampling, quantization, and encoding.

8. Some ADCs use a sample-and-hold circuit to maintain the input voltage constant during conversion.

9. Different architectures like SAR, Sigma-Delta, Flash, or Dual Slope use varying techniques to achieve this process.

10. The resulting digital output can be read by a microcontroller, processor, or digital system for further processing, storage, or transmission.

11. Applications of ADC in Electronics

• To capture and digitize high-frequency analog signals for measurement and analysis, ADCs are used in digital oscilloscopes and signal analyzers.

• ADCs are essential in data acquisition systems (DAQ) for converting sensor signals like temperature, pressure, and humidity into digital form.

In this tutorial you will learn how to use an Infra-Red Sensor in combination with Nuvoton Board. At the end of this tutorial, you will be able to build any project with a Nuvoton board and various types of Sensor to read and encode them.

In this project we will be using IR sensors and Nuvoton MS51FB9AE Development Board.

Before continuing to build the project let’s know about what IR is and where it can be used.

What is Infrared Radiation (IR)?

• Wavelength infrared: 700nm to 1000nm

• Human visible wavelength: 400nm to 700nm

What is an IR Sensor?

An IR sensor is a device that can measure the infrared radiation in its surroundings and gives an electric signal as an output. An IR sensor can also be used for the detection of motion of the objects which are in the line of sight with the sensor.

As the infrared radiation is invisible to human eyes, it can be detected by the infrared sensor. An IR sensor is a photodiode that is sensitive to the IR light. When IR light falls on the photodiode, the resistances and the output voltages will change in proportion to the magnitude of the IR light received.

Features:

• The operating voltage is 5VDC

• I/O pins – 3.3V & 5V

•  Mounting hole

• The range is up to 20 centimeters

• The supply current is 20mA

• The range of sensing is adjustable

• Fixed ambient light sensor

An integrated circuit (IC) known as a microcontroller is a compact, inexpensive, and self-contained computer that is used in embedded systems to carry out a specified purpose. A microcontroller, often known as an MCU or microcontroller unit, is essentially a tiny computer built into a single chip. It can alternatively be described as a programmable silicon chip that is clock-driven, register-based, accepts input, processes it in accordance with instructions stored in memory, and outputs the results.

A computer is a multipurpose device that may be used for many different tasks, including word processing, watching movies, editing videos, accessing the web, and producing software. While a microcontroller from top manufacturers Nuvoton and Mind Motion is designed to perform a variety of specific functions, such as managing an air conditioner or a washing machine. Keep reading this blog to understand the various uses, advantages, and characteristics of microcontrollers.

How Does Microcontrollers Work?

 Utilizing its CPU, a microcontroller processes data sent to its input ports and outputs the result via output pins. A synchronous sequential logic circuit powers or drives it.

A sequential circuit is a logical circuit whose output depends on both the present inputs and the history of the inputs, according to the theory of digital circuits. Additionally, in synchronous sequential circuits, a clock signal-determined discrete timing is used to determine when a device's state changes. When compared to an asynchronous system, the fundamental benefit of a synchronous system is its simplicity.

I assume you are aware of the propagation delay. A microcontroller processes data using a huge number of logic gates. Propagation delay is the amount of time it takes for these gates to alter their output state in response to their inputs. To ensure that the logic circuit is robust and dependable, the time between each clock pulse should be higher than this propagation delay. Thus, this establishes a microcontroller's maximum operating speed, which varies between microcontrollers.

What Are the features Of Microcontrollers?

 Top characteristics or features of Microcontrollers are:

High Functional Integration

Because microcontrollers feature on-chip memory, I/O circuitry, and other circuitries that allow them to operate as miniature standalone computers without additional supporting circuitry, they are referred to as single-chip computers.

Flexibility and Field Programmability

Microcontrollers frequently use EPROM or E PROM as their storage device to enable field programmability and make them more usable. Numerous microcontrollers can be programmed for use in embedded systems once the program has been verified to be accurate.

What Are The Elements Of Microcontroller?

 A microcontroller, as we have already mentioned, contains a variety of components, including a CPU, RAM, and ROM.

CPU

CPU is a computer's equivalent of the processor, which is made up mostly of the Arithmetical and Logical Unit (ALU), Control Unit, and Register Array. The arithmetic and logical operations of the information received from input devices or memory are carried out by the ALU, as its name suggests. A register array is made up of a collection of registers, such as accumulators (A), B, C, and D, that serve as temporary fast-access memory locations for data processing. The control unit, as its name suggests, regulates how information and instructions move throughout the system.

RAM

RAM Random Access Memory is referred to as RAM. RAM is used to store data dynamically while the microcontroller is carrying out instructions, just like a computer would. Since it has a volatile memory, all of the data is lost when the power is turned off.

Program Memory, or ROM

Read-Only Memory is referred to as ROM. Flash memory was once programmable in older microcontrollers, which is why it is known as ROM. However, the most recent microcontrollers—EEPROMs—allow for reprogramming (Electrically Erasable Programmable Read Only Memory). The program or instructions that must be performed are stored in ROM.

Input Output Ports (I/Os)

Microcontrollers include a number of general-purpose input-output (GPIO) pins that can be configured as input or output pins by writing to certain configuration registers. These pins are referred to as input-output ports (I/Os). This pin can interact with the outside world by reading or writing HIGH or LOW states from or to its pins.

Clock

As it operates and is guided by sequential logic as previously described, a microcontroller needs a clock. The source of the clock can be internal, like an RC oscillator, or external, like a crystal oscillator. The clocking choices available to different microcontrollers will vary. Some cutting-edge microcontrollers even come equipped with internal PLLs or FLLs that can multiply the clock to higher frequencies.

Peripherals

Microcontrollers will also have the following peripherals.

·        To communicate serially, use UART, SPI, or I2C.

·        Timers/Counters

·        Take-and-compare-and-PWM modules

·        Digital to Analog Converter

Benefits of Microcontrollers

 It is important to keep in mind, that you can only benefit from microcontrollers if they are from trusted manufacturers like Nuvotonand MindMotion, as they offer you ease, durability and toughness, unlike others. Here are the top benefits of Microcontrollers-

Little Size

A microcontroller, as opposed to a computer microprocessor, is designed to do certain functions. Therefore, there are very few hardware requirements in terms of RAM, ROM, and other peripherals. Thus, by drastically lowering the overall size, everything is incorporated into a single chip.

Low Cost

Microcontrollers are extremely affordable as compared to microprocessors since they have fewer peripherals, RAM, and ROM built onto a single chip.

Lower Energy Consumption

Because a microcontroller uses a smaller set of hardware, including RAM, ROM, and other peripherals contained in a single chip, it consumes relatively little power.

Conclusion

 The processing instrument known as the microcontroller is quite handy. The architecture clearly identifies the microprocessor's area of expertise, but it also comes with a few usage drawbacks. However, microcontrollers from popular brands like Nuvoton and MindMotion are quite practical and helpful for small or microdevices. Additionally, the fact that they have been updated and always undergo fresh peripheral development makes them an amazing choice for usage in micro appliances.
