Question: Discuss your understanding on MOSFET detailing the types, construction and characteristics.

MOSFET

• MOSFET (metal oxide semiconductor field effect transistor) is a second category of field effect transistor. The MOSFETs, compared to BJTs, can be made very small and hence can be used to design high density VLSI circuits.

• The MOSFET has no pn junction structure; instead, the gate of the MOSFET is insulated from the channel by a silicon dioxide (SiO₂) layer. Due to this the input resistance of MOSFET is very high.

• Because of the insulated gate, MOSFETs are also called IGFETs. The two basic types of MOSFETs are depletion (D) MOSFET and enhancement (E) MOSFET.

Review Question

1. Discuss your understanding on MOSFET detailing the types, construction and characteristics.
