ing. The total charge on capacitors and immediately before and
after switching is computed and plotted in Fig.7.20.
The sensitivities of the output voltage with respect to conductor
and capacitor were calculated using sampled-data simulation with
the same settings as those used in response simulation. They were also
calculated using the brute-force method as follows
