Field Effect Transistors (FET) - Technical MCQs

Q1:

A very simple bias for a D-MOSFET is called:

A self biasing

B gate biasing

C zero biasing

D voltage-divider biasing

ANS:C - zero biasing

Zero biasing means without applying any voltage can flow the current in the circuit. In D- MOSFET construction having let us take n-type, the n-type semiconductor material is diffused b/w the two highly dopped n-type materials. That's why the vgs=0 some drain current having it clearly shows the characteristics of the D-MOSFET.
