in terms of cost and performance. As a result, we are not going to study parametric
programmable SC filters in detail; the interested reader is referred to [16][17][18][19].
Sometimes a programmable capacitor array may also be used as the input stage for
binary-weighted data converters.
Lastly, it can be proved that the maximum magnitude/voltage gain (G)of an
SC biquad also depends on capacitance ratios (assuming Tis a constant). For the
sake of brevity, the proof is left to the interested reader as an exercise (Hint:
Consider the dimensions of system coefficients such as aand b [20]). As a rule o ...
