A feedback amplifier is provided with a voltage-controlled compensation circuit which varies the effective feedback capacitance by controlling a proportional amount of feedback current returned via the capacitor to the amplifier summing node. The proportionality and current steering of the feedback current is effected by a multiplier circuit, the bias of which is controlled by an adjustable DC voltage. Several feedback amplifier configurations are shown herein, exemplifying the versatility of the compensation circuit of the present invention.
