that switch sharing is employed), whereas the second stage is realized based on the
Type-2 biquad shown in Figure 4.3. Additionally, note that the filter output jumps
only during the P
2
phase.
The next step is to use dynamic range scaling to scale the peak output voltage of
each op-amp. Figures 4.9(a) and (b) illustrate the output of each op-amp before and
after scaling, respectively. The peak op-amp output voltages before scaling shown in
Figure 4.9(a) are obtained from SWITCAP (see Chapter 3) simulation based on the
circuit shown in Figure 4.8, using the initial capacitance values calculated by
(a) ...
