and substituting this value in (1.38) we get the well-known expression for
the transconductance
Another useful expression for
can be found by comparing (1.38) with
(1.33) thus obtaining
The second dependent current source,
accounts for the body effect
and its transconductance is defined as
The first derivative in (1.42) results as
while the second one comes out by deriving (1.35) with respect to
thus
yielding
Therefore, substituting (1.43) and (1.44) in (1.42) we get
