Question

What is depletion mode and enhancement mode?

Answer 1

Depletion mode-the device normally ON at zero gate - source voltage.
Enhancement mode-the device normally OFF at zero gate-source voltage.

Answer 2

$\huge{ \boxed{ \bf{Answer :}}}$

• In field-effect transistors, depletion mode and enhancement mode are two major transistor types, corresponding to whether the transistor is in an ON state or an OFF state at zero gate-source voltage.
• Enhancement-mode MOSFETS are the common switching elements in most integrated circuits.
