Abstract
A plurality of input stages having their outputs connected to provide differential currents to a load. When a bias current flows through a selected one of the input stages, the differential currents are provided in response to a differential signal provided to the selected stage. The input stages are each comprised of a pair of emitter-coupled transistors. Resistors are connected in series with the emitters of the transistors and the bias current is directly proportional to absolute temperature. The resistors may be adjusted to cause the offset voltages of the input stages to substantially equal zero at all temperatures.
