What is CG amplifier?

In electronics, a common-gate amplifier is one of three basic single-stage field-effect transistor (FET) amplifier topologies, typically used as a current buffer or voltage amplifier. In this circuit the source terminal of the transistor serves as the input, the drain is the output and the gate is connected to the ground, or "common," hence its name. The analogous bipolar junction transistor circuit is the common-base amplifier.
