Draw a NMOS common-drain amplifier using an ideal resistance R₂ as load. Consider the bulk and source are shorted. Draw the small signal equivalent circuit and determine the gain in terms of Rs and gm (here gm is the transconductance of the PMOS) When Rs >> 1/9m what is another popular name for this amplifier? Mention one advantage of this design compared to a NMOS version.

Draw a NMOS common-drain amplifier using an ideal
resistance R₂ as load. Consider the bulk and source are
shorted.
Draw the small signal equivalent circuit and determine the gain
in terms of Rs and gm (here gm is the transconductance of the
PMOS)
When Rs >> 1/9m what is another popular name for this
amplifier? Mention one advantage of this design compared to a
NMOS version.
