Answer 1

There are three types of FET amplifiers depending upon the common terminal used as input and output.
In a common gate amplifier, the gate terminal is common to both input and output.
In a common source amplifier, the source terminal is common to both input and output.
In a common drain amplifier, the drain terminal is common to both input and output. It is also known as a "source follower."
Answer: common base.
