FIGURE 3-7:
Figure 3-8 shows the step response of the filter in Figure 3-1. The output of U
second op amp) shows the largest overshoot, so it limits the output voltage range of
the filter. The nominal overshoot is 6.1% (0.18V for a 3.0V step).
FIGURE 3-8:
Many SPICE simulators support Monte Carlo simulations. Using this capability on your
design will help determine what tolerances are needed on your design. The same
results can be obtained by measuring many filters (i.e., 30 to 10,000), but at a greater
cost.
