Complementary Metal Oxide Semiconductor (CMOS)

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. One way to reduce the current drain of a digital circuit is with complementary MOS (CMOS). Complementary metal oxide semiconductor devices are chips in which …

Enhancement Type MOSFET – Construction, Operation and Characteristics

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 it was part of the evolution towards the E-mode MOSFET, a device that has revolutionized the electronic industry. Enhancement Type MOSFET has become enormously important …

Depletion Type MOSFET – Construction, Operation and Characteristics

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 increased. The increase in the depletion regions reduces the channel thickness, which increases its resistance. The net result is that drain current ID is reduced. …

Metal Insulator Semiconductor Field Effect Transistors (MISFETs)

Metal Insulator Semiconductor Field Effect Transistors (MISFETs): The Metal Insulator Semiconductor Field Effect Transistors (MISFETs) is one of the most widely used electronic devices, particularly in digital circuits, because of relatively small size-thousands of devices can be fabricated in a single integrated circuit (IC). Since it is constructed with the gate terminal insulated from the …
