Alternatively, coefficients and can be obtained directly from (2.32) and
(2.33) if we consider that we have to substitute
and
with
and
respectively, to evaluate the equivalent resistance seen by capacitors
and
Besides, the equivalent resistance seen by capacitance
after
neglecting transconductance
and resistance
is equal to
In fact, considering the small-signal circuit in Fig. 2.13, we get
and
Coefficient can be obtained directly from (2.34) by substituting the
transconductance
with its equivalent
in the common X configuration
with a degenerative resistance
