This article is on MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistor), covering the difference between D-MOSFET and E-MOSFETs with construction, working, advantages, disadvantages, and applications. MOSFETs are the most common types of Field Effect Transistors (FETs) in Modern electronics. It functions as a voltage-controlled device and delivers high input impedance along with fast switching speed. MOSFETs are the […]
A phototransistor is a semiconductor device that combines the properties of a photodiode and a transistor. It is sensitive to light and provides amplified electrical output based on the light intensity incident on its base region. Phototransistors play a vital role in optoelectronic applications such as light sensing, encoders, switches, and signal transmission, owing to […]
In power electronics, the SCR, DIAC, and TRIAC are three common semiconductor devices that are very useful in electric power control and conversion applications. Though they all belong to the thyristor family, their operation, structure, and applications differ significantly. Here’s a detailed explanation of SCR (Silicon Controlled Rectifier), DIAC (Diode for Alternating Current), and TRIAC […]
Dual power supply circuit is the backbone of many electronic systems. Various circuits, especially those involving operational amplifiers, analog devices, and certain digital systems, require both positive and negative voltages to operate properly. This is where Dual Power Supply Circuits come into play. They provide symmetrical voltages (like +12V and -12V, +15V and -15V, etc.) […]
Data transmission is the fundamental process of transferring digital or analog data between two devices.
