SECOND_ORDER_VOLTAGE_CONTROLLED_FILTER

Published:2009/6/19 1:55:00 Author:May | From:SeekIC

Desirable second-order voltage-controlled low-pass filter response can be achieved with this voltage-controlled filter (A). By using low-distortion, wide-bandwidth multipliers, it achieves higher cutoff frequencies than sv(itched-capacitor filters. If the circuit's RC network has a time constant less than 200 ns, it should be replaced by a lag compensator network (B).
