Abstract
Electronic gain control is achieved by means of a differential controller in combination with a multistage, feedback amplifier. Both the input impedance and the output impedance have a low ohmic value, so that the influence of parasitic capacitances in the differential controller on the bandwidth is significantly reduced.
