Hence, the feedback circuit can then be schematised by the block diagram in
Fig. 7.14, where the blocks inside the shadowed area represent the linear and
nonlinear contributes of the RC output node, with the nonlinear coefficients
given by
To evaluate the closed-loop harmonic distortion factors we can employ
the results found at the end of section 7.2.2. After applying (7.55) and (7.56)
we get the following equations in which
and
(expressions in terms of
only are reported for compactness).
