We set then taking into account the load effects (input
resistance of T1 and output resistance of T3), the circuit small-signal model
depicted in Fig. 6.21 is considered. The feedforward transresistance and the
corresponding input and output resistances are

Set to zero and replace the controlled current generator with an
independent current source,

. Transistor T1 can be considered switched off,
and the resulting AC model is that in Fig. 6.22, which leads to the small-
