Question

Difference between common source common drain and common gate amplifier

Answer 1

This is the same as for a BJT. The devices have different parameters but the general function is the same in the linear region.

Common Source: The most used gain stage. Especially the differential version (diff pair) for many analog circuit.

~Can develop gain.
~High input impedance.
~Inverting.

Common Drain: Buffer configuration. Source follower is another name for that reason (the source follows the gate).

~Near unity gain (some loss, but more loss with finer process nodes due to poor device gain)
~High input impedance. (good for buffers)
~Low output impedance. (good for buffers)~Good linearity (relative to the other topologies at least)
~Non-inverting.
