## How does MOSFET control voltage?

MOSFETs have also been used as voltage-controlled resistors. Because most MOSFETs today tend to be “enhancement mode”, this means that the required biasing at the gate is a positive voltage to turn on the drain current to lower its Rds. Thus, if the gate voltage is 0 volts, the MOSFET is turned off.

## How MOSFET acts as an amplifier?

A small change in gate voltage produces a large change in drain current as in JFET. This fact makes MOSFET capable of raising the strength of a weak signal; thus acting as an amplifier. During the positive half-cycle of the signal, the positive voltage on the gate increases and produces the enhancement-mode.
