MOSFET Full Form is Metal Oxide Semiconductor Field Effect Transistor. Here we will be discussing MOSFET VI Characteristics, symbol and its classification. They are broadly classified into two types namely enhancement Type and depletion type MOSFET. In an enhancement type MOSFET channel has to be induced for the device to conduct, which is achieved by […]

Schmitt Trigger Circuit Working and Applications
A Schmitt Trigger circuit is a comparator circuit with some modifications. As compared to a normal comparator circuit the Schmitt trigger circuit has a hysteresis curve. This means that it has two threshold voltages an upper threshold and a lower threshold voltage. In Schmitt trigger hysteresis is created by applying positive feedback to the non-inverting input […]
Gunn Diode Working Principle VI Characteristics & Applications
Gunn diode operates on the Gunn effect which is named after its inventor J.B. Gunn. He discovered the periodic variation of current in a GaAs (gallium arsenide) rod in 1963. The microwave device that operates on the principle of transfer of electrons is called as Gunn diode. This is one of the diodes used as […]
VI Characteristics of IGBT and it’s Working Principle
The VI characteristics of IGBT is as shown in Figure. In the forward direction, they are similar to those of bipolar transistors. The only difference here is that the controlling parameter is the gate to source voltage Vgs and the parameter being controlled is the drain current. The working principle of IGBT is based on […]
IGBT-Insulated Gate Bipolar Transistor its Working and Applications
An insulated-gate bipolar transistor (IGBT) is a three-terminal semiconductor device it is a hybrid of MOSFET and BJT for high efficiency and fast switching. The power BJT has the advantage of low on state power dissipation, but it cannot be switched at faster rates due to longer turn-off time, whereas MOSFETs have a very high […]
Triac Working, Structure, VI Characteristic and Application
A Triac is a bidirectional device it allows current to flow in both the directions. here we will discuss Triac working and vi characteristics, In the SCR family, after the SCR, Triac is the most widely used device for power control. Triac is a three-terminal device, with the terminals named as main terminals 1, 2 […]
