## 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.
