MOSFET Amplifier Question & Answers

October 10, 2022 By WatElectronics

This article lists 50 MOSFET Amplifier MCQs for engineering students. All the MOSFET Amplifier Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of the MOSFET Amplifier.

A MOSFET is an electrical device abbreviated as  Metal Oxide Field Effect Transistor. This device comprises 3 main terminals namely source, drain and gate; out of which the gate terminals voltage assists in finding out the device conductivity.

In other words, varying the voltage varies the conductivity of the device. They are classified as Enhancement type and depletion type MOSFET of either  NMOS or PMOS. MOSFET operates in saturation/active region and provides a perfect Q-based point.

The voltage gain of a MOSFET Amplifier includes 1/gm. Where the gm is the gain. The advantages of a MOSFET amplifier include minimum losses, max speed, and minimum power consumption. The disadvantages of the MOSFET Amplifier include the cost of design and minimum gain.

The applications of MOSFET amplifiers include RF, sound systems, and choppers.
