Question

A gate to drain-connected enhancement mode MOSFET is an example of
1. an active load
2. a switching device
3. a three-terminal device
4. a diode

Answer 1

Correct Answer - Option 1 : an active load

Active load:

In-circuit design, an active load is a circuit component made up of active devices, such as transistors, intended to present a high small-signal impedance yet not requiring a large DC voltage drop, as would occur if a large resistor were used instead.

When the drain and gate of a MOSFET are connected together, then a two-terminal device known as a “diode-connected transistor” results, which acts like an active load.
