Abstract

In accordance with the teachings of this invention, a novel wide-band, DC coupled, single-ended voltage-to-current converter and gain control circuit is provided. Of importance, the circuit of this invention is designed to receive an input signal referenced to ground such that for zero input current, zero output current is provided. A replica bias circuit is used which allows the output signal to be a function of the input signal without offsets introduced by bias currents used throughout the circuit.
