The closed-loop Miller-compensated amplifier can then be modeled as
depicted in Fig. 7.12, where the amplifier studied above is closed in a loop
with feedback block f. Note that to further simplify the scheme, Fig. 6.12b
includes the new nonlinear block with its nonlinear coefficients
and defined above. Moreover, for conformity
with the notation used in the previous section, we define the gain of the first
block,
h,
as equal to
Gain
h
in Fig. 7.12b is equal to
and coefficients
are defined in
(7.65-(7.67).
From relationships (7.50)-(7.51a), and given that
we get the
second and third harmonic distortion factors
