12.1.2 Small-Signal Model
Similarly to what we have seen for the BJT, the AC response of the MOSFET also
can be expressed in terms of two-port small-signal equivalent circuit. The choice
can be among the six different topologies already discussed (Section 5.4.1 in
Chapter5), all of which are possible and useful. But, it is better to select the topol-
ogy that better ties with the theory of the device. In particular, for the input loop,
the presence of the oxide prevents any current owing through the gate, which can
be considered an open circuit. For the output loop transconductance g
m
imposes
the presence ...
