Abstract :
The effect of pole zero pairing on the total capacitance of cascaded biquad SC filters is investigated. It is shown that significant reductions in total capacitance and hence corresponding reductions in silicon area are possible through optimal pole-zero pairing without causing significant degradations in filter performance.
