Abstract
An amplifier includes differential current sensing circuitry and an input bridge. Two paths of the input bridge receive the input signals and provide proportional current flows to the differential current sensing circuitry. The input bridge is configured to provide a differential offset voltage in one current path, and a complimentary voltage drop of equal magnitude in the other current path. In the examples, the input bridge includes a matched pair of transistors. To remove parallel incremental or small-signal conductance-related error sources, both transistors are operated at matched V(drain-to-source) voltages. The voltage offset, provided in association with one of the input transistors, serves to extend the range of certain circuits using the amplifier. The complimentary voltage drop in association with the other input transistor maintains the match of the Vvoltages for the two transistors.
