Complementary Metal Oxide Semiconductor (CMOS): With active load switching, the current drain with a low output is approximately equal to ID(sat). This may cause a problem with battery operated equipment.…
N Channel Power MOSFETs or V-MOSFET or V-FET: N Channel Power MOSFETs - Power MOSFETs are usually constructed in V-configuration, as shown in Fig. 13.94. That is why, the device is…
Enhancement Type MOSFET - Construction, Operation and Characteristics: Although DE-MOSFET is useful in special applications, it does not enjoy widespread use. However, it played an important role in history because…
Small Signal Model of MOSFET: If the small bulk resistances of the source and drain are neglected, the Small Signal Model of MOSFET and its equivalent circuit between terminals G…
Depletion Type MOSFET - Construction, Operation and Characteristics: As we know already that when the gate is biased negative w.r.t. the source in an N-channel JFET, the depletion-region widths are…
FET as a Voltage Variable Resistor (VVR): FET is a device that is usually operated in the constant-current portion of its output characteristics. But if it is operated in the…
Applications of FETs (Field Effect Transistors): Applications of FETs - FET has a very high input impedance (100 MΩ in case of JFETs and 104 to 109 MΩ in case of…
Generalized FET Amplifier Circuit: The analysis of a common source amplifier with a source resistance RS, a common gate amplifier and a common drain amplifier at low frequencies may be…
