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.…
What is MOS Capacitor? The metal-oxide-semiconductor MOS capacitor shown in Fig. 13.92 (a) is the heart of the MOSFET. The metal may be aluminium or some other type of metal.…
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…
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…
Small Signal Model of FET: The Small Signal Model of FET which consists of Low Frequency Small Signal Model for FET and High Frequency Model for FET. Low Frequency Model:…
FET Biasing Methods - Fixed Bias, Self Bias, Potential Divider Bias and Current Source Bias: Unlike BJTs, thermal runaway does not occur with FETs. However, the wide differences in maximum…
Self Bias or Potential Divider Bias Circuit: This is the most commonly used biasing arrangement. The arrangement of Self Bias or Potential Divider Bias Circuit is shown in Fig. 12.17…
