MOSFET DEVICE PHYSICS 2

which component is considered to be an OFF device?

• D-MOSFET

• BJT

• UJT

• E-MOSFET

In an E only MOSFET, drain current starts only when Vgs is

• positive

• negative

• zero

• greater than Vgs(th)

The main factor which makes a MOSFET likely to breakdown during the normal handling

• very low gate capacitance

• high leakage current

• high input resistance

• very low gate capacitance and high input resistance

The input impedance of a JFET is compared to an ordinary transistor is

• equal

• less

• more

• none of the mentioned

The main advantage of CMOS is its

• High power rating

• Small-signal operation

• Switching capability

• Low power consumption

Most small-signal E-MOSFETs are found in

• Heavy-current applications

• Discrete circuits

• Disk drives

• Integrated circuit

CMOS devices use

• Bipolar transistors

• Complementary E-MOSFETs

• Class A operation

• DMOS devices

The gate of a JFET is biased

• reverse

• forward

• reverse as well as forward

• none of the mentioned

A D-MOSFET is considered to be a

• Normally off device

• Normally on device

• Current controlled device

• High-power switch

CMOS stands for

• Common MOS

• Active-load switching

• p-channel and n-channel devices

• complementary MOS
