Abstract

A circuit includes a differential circuit having at least to two inputs, a first variable impedance circuit, and a second variable impedance circuit. The first variable impedance circuit is between a first branch of the differential circuit and an output. The first variable impedance circuit provides a first variable impedance. The a second variable impedance circuit is between a second branch of the differential circuit and the output. The second variable impedance circuit provides a second variable impedance. The first variable impedance and the second variable impedance vary in accordance with a voltage difference between the two inputs.
