In these two cases (5.78) respectively becomes
It is worth noting that the above expressions have exactly two poles thanks
to the action of the ideal buffers. Both second poles are also negative. The
second pole in (5.79) can be simply interpreted by analysing the circuit in
Fig. 5.15, where the inner amplifier,
through the capacitive network, acts
as a
multiplier by a factor equal in module to
The
