Introduction to TTL and CMOS Logic Gate Circuits24 November 2025
Electronic circuits that implement basic and common logic operations are called logic gate circuits. TTL and CMOS logic gate circuits are 2 typical types. Read this to learn their structure and features.
Bluetooth Explained: Characteristics and Applications02 June 2021
Bluetooth is a global specification of wireless data and voice communication, which is a special close-range wireless technology for setting communication environments for fixed and mobile devices. Bluetooth allows some of the current portable mobile devices and computer devices to connect to the Internet without a cable and can be wirelessly accessing the Internet.
8051 Microcontroller: History, Architecture, Applications, and Features20 February 2021
The 8051 Microcontroller Introduction and some of its basic features are discussed in this article.
What is a Polypropylene Capacitor?08 November 2021
A polypropylene capacitor is a kind of capacitor with a very stable electric capacity. It is often used in applications requiring very precise capacitance and can replace most polyphenylene or mica capacitors.
Operational Amplifier Basics: Working Principle and Amplifier Circuit21 March 2025
Operational amplifier (referred to as "op amp") is a circuit unit with very high magnification. In actual circuits, a certain functional module is usually combined with a feedback network. It is an amplifier with a special coupling circuit and feedback. The output signal can be the result of mathematical operations such as addition, subtraction, differentiation, and integration of the input signal. Because of its early application in analog computers to realize mathematical operations, it was named "operational amplifier".
A/D Converter: Basic Principle and Types06 November 2020
An analog-to-digital converter, or A/D converter, or ADC for short, is usually an electronic component that converts an analog signal into a digital signal. A typical analog-to-digital converter converts an input voltage signal into an output digital signal.
Is there a Limit to the Chip Process Node?02 November 2021
Process node refers to the spacing between circuits within an integrated circuit, specifically, the line width of the gate in the transistor structure, which is the value in the XXnm process. The narrower the width, the lower the power consumption.
What is Tantalum Capacitor: Structure, Failure and Application Guide14 April 2022
Hello everyone, I am Rose. Welcome to the new post today. Today I will introduce tantalum capacitors to you. This article includes its structure, production process,failure mode, precautions and application guide and so on.
RVDT(Rotary Variable Differential Transformer) Basics02 February 2021
The Rotary Variable Differential Transformer or RVDT is regarded as the transformer that detects the angular displacement of the conductor. That is the kind of electromechanical transducer that gives the angular displacement of the input equal to the linear output.
Millimeter Wave Radar: Advantages, Types, and Applications18 October 2021
Millimeter wave radar is a radar that works in millimeter wave. Millimeter waves refer to the 30 ~ 300GHz frequency domain (the wavelength is 1 to 10 mm). The wavelength of millimeter waves is between microwaves and centimeters, so millimeter wave radar has some advantages of microwave radar and photoereta.
What is a Decoder?09 January 2026
A decoder is a type of circuit that can translate the state of the input binary code into an output signal to express its original meaning. It can be said that the circuit that realizes the specific meaning of the code state is called a decoder.
What is a SAW Sensor? Types, Working and Applications29 March 2021
The SAW (Surface Acoustic Wave) sensor is a new type of micro-sensor that has developed in recent years. It is an acoustic surface wave device as a sensor element that will be measured through the acoustic surface wave device. The speed or frequency of the wave is reflected and converted into the sensor output by the electrical signal.
