Introduction to FinFET18 March 2021
The full name of FinFET is Fin Field-Effect Transistor. It is a new complementary metal oxide semiconductor transistor. The FinFET name is based on the similarity between the shape of the transistor and the fin.
LDR/Light Dependent Resistor: Working Principle, Types and Applications19 January 2026
In general, the control of lights and home appliances is manually operated and maintained on a number of occasions. However, due to the carelessness of human beings or unusual conditions, the process of controlling appliances may cause power wastage. We can use the light-dependent resistor circuit to control loads based on the intensity of light to overcome this problem. A device made of high-resistance semiconductor material is an LDR or a photoresistor. This article provides an overview of LDR, the light-dependent resistor circuit and its operation.
Sensor Basics: Classification, Working Principle and Application02 April 2025
A sensor is a detection device that can sense the measured data and convert it into electrical signals or other required forms of information output according to particular rules, in order to meet the requirements of data transmission, processing, storage, and display, as well as recording and control. Sensors are frequently categorized based on their functioning principle, input data, and application scope. They may be loosely split into three types based on their diverse functioning principles: physical type, chemical type, and biological type.
Introduction to DDIC (Display Driver IC)07 January 2026
Driver IC is an integrated circuit chip that controls the switching and display method of LCD panels and AMOLED panels. With the increase of panel display resolution and data transmission speed, the requirements for driver ICs are also increasing.
Voltage Follower: Purpose, Working, and Circuits27 March 2025
An op-amp circuit is a voltage follower (also called a unity-gain amplifier, a buffer amplifier, and an isolation amplifier). This suggests that the op-amp would not supply the signal with any enhancement. This article addresses the voltage follower description.
What is a Variable Resistor?26 April 2025
With a variable resistor, you can readily adjust the resistance, and therefore the current, of a circuit for functions such as dimming lights, controlling the speed of a motor, or adjusting a signal generator. This article will explain the symbols, construction and types of variable resistors and how potentiometers (three-terminal variable resistors) can be used as adjustable voltage dividers.
Surge Protection Devices (SPD): The Complete 2025 Guide25 December 2025
A surge protection device (SPD), also called a surge protector, is an electronic device that provides safety protection for various electronic equipment, instruments, and communication lines. When a spike current or voltage is suddenly generated in the electrical circuit or communication circuit due to external interference, the surge protection device can conduct and shunt in a very short time, so as to prevent the surge from damaging other equipment in the circuit.
Beginners Guide to Precision Resistors10 April 2025
Precision resistors refer to resistors whose resistance value tolerance, thermal stability (temperature coefficient), and distributed parameters(distributed capacitance and distributed inductance) all meet certain standards.
Solenoid Switch: Working Principle, Types and Applications03 February 2021
A solenoid switch is an electrical switch that is often used where a high current circuit, namely a starter motor circuit, is brought into operation with the aid of a low current switch. This switch switches a durable switch on to connect the vehicle's battery to the starter of the motor. A solenoid switch attaches the drive pinion to the starter until the ignition key is triggered. High performance, reliability, and longevity are the key characteristics of solenoid switches.
What is a Water Level Indicator?19 February 2021
A water level indicator is a system that relays information back to a control panel to indicate whether there is a high or low water level in a body of water. A combination of probe sensors or float switches to sense water levels is used for some water level indicators.
Schottky Diodes: Principle, Functions, and Applications21 October 2025
Schottky diodes are metal-semiconductor devices made of precious metals (gold, silver, aluminum, platinum, etc.) A as the positive electrode and N-type semiconductor B as the negative electrode. Schottky diodes are unidirectionally conductive and can convert alternating currents into pulsed direct currents in a single direction.
