What are Avalanche Diodes?02 April 2020
Avalanche diodes are semiconductor devices that use the avalanche multiplication effect and carrier transit time effect in the PN junctions to generate microwave oscillations. If a large reverse voltage is applied across the diode, the space charge region is widened from the N + P junction to the IP + junction. The electric field in the entire space charge region is the largest at N + P. If the electric field intensity exceeds the breakdown electric field in a small area near the N + P junction, then this phenomenon is called avalanche breakdown and the area where it occurs is the avalanche region.
Car Sensors: Classification and Application27 October 2025
The car sensor is the input device of the automotive computer-controlled system. The earliest car sensors are oil pressure sensors, oil quantity sensors, and water temperature sensors connected to instruments or indicator lights in the 1960s. There are many kinds of car sensors like temperature sensors, pressure sensors, flow sensors, etc., and they are applied in different applications according to their specific properties.
Introduction to TVS Diodes07 August 2020
TVS diodes (Transient voltage suppression diodes), also called clamp diodes, are electronic parts for protection, which can protect electrical equipment from voltage spikes introduced by wires. It is a high-performance circuit protection device commonly used internationally.
Introduction to PIC Microcontroller: Architecture, Features, and Applications08 April 2025
The world's smallest microcontrollers that can be programmed to execute a wide variety of tasks are PIC (Programmable Device Controllers) microcontrollers. In several electronic gadgets, such as phones, machine control systems, warning systems, embedded systems, etc., these microcontrollers are included. There are various types of microcontrollers, even though the best are found in the programmable microcontroller range of GENIE. This microcontrollers are programmed and simulated with software from a circuit wizard.
What Is a Decoupling Capacitor? Function, Placement, and Selection Guide14 July 2026
In electronic circuits, it is often seen that there is an electrolytic capacitor near the power supply pins of the integrated circuit. This capacitor is a decoupling capacitor. Decoupling capacitors usually have two functions: one is energy storage, and the other is to remove high-frequency noise.
Ceramic Capacitor Dielectrics Explained: C0G, X7R, Y5V and How to Choose14 July 2026
A ceramic capacitor is also called a monolithic capacitor, whose dielectric material is ceramic. According to the different ceramic materials, it can be divided into two types: low-frequency ceramic capacitors and high-frequency ceramic capacitors. According to the structure, it can be divided into wafer capacitor, tubular capacitor, rectangular capacitor, a chip capacitor, feedthrough ceramic capacitor and so on.
RTD Sensors: Working Principle, Features and Applications22 May 2025
The term RTD stands for Temperature Detector for Resistance. This sensor is also known as a thermometer for resistance. To calculate the temperature, this sensor is used. They are typically available as a piece of fine wire made of nickel or copper platinum, wound around a heart of ceramic or glass. To calculate the temperature, this sensor makes use of the wire's temperature/resistance relationship.
What is an Inductive Sensor?31 October 2025
An inductive sensor is a device to realize non-electric measurement by using the change of coil self-inductance or mutual inductance. Using inductive sensors, displacement, pressure, vibration, strain, flow and other parameters can be measured. It has a series of advantages such as simple structure, high sensitivity, large output power, small output impedance, strong anti-interference ability, and high measurement accuracy, so it is widely used in the electromechanical control system.
Tantalum Capacitors Explained: How They Work, Where They Fit, and How to Use Them Safely14 July 2026
Tantalum capacitors sit in an interesting spot in the design engineer's parts bin. They pack a large amount of capacitance into a small, stable, board-friendly package, yet they carry a reputation for failing dramatically when mistreated. Both halves of that reputation are true, and neither tells the whole story. Used within their ratings, tantalum capacitors are dependable workhorses; used carelessly, they can short and overheat. This guide walks through what they actually are, how the two main families differ, how they compare with aluminum electrolytic and ceramic parts, and the engineering discipline that keeps them reliable.
EMI Filter: Introduction, Functions and Applications23 December 2020
Electromagnetic interference filter, also known as "EMI filter" is an electronic circuit device used to suppress electromagnetic interference, especially noise in power lines or control signal lines. The EMI filter functions as two low-pass filters: one is to attenuate common mode interference, and the other is to attenuate differential mode interference. It is top choice for electronic equipment design engineers to control conducted electromagnetic interference and radiated electromagnetic interference.
