SIM983 Scaling Amplifier
top end of the range for BWTH
Section 5.1.2.5, the amplifier is relatively overcompensated, result-
ing in an increased settling time. Compare with Figure 4.3, with
G 10 00 at the low end of the range for BWTH
relatively undercompensated, and the smaller phase margin results
in some overshoot and ringing.

The asymmetrical positive-going and negative-going responses
in Figures 4.5 and 4.6 are ultimate artifacts of the single-ended,
as opposed to di erential, topology of the input voltage bu er
(Section 5.1.2.1).
