ABSTRACT:
Disclosed is a circuit and method for compensating DC output level variations in a differential emitter-coupled logic circuit. The DC output level compensating differential emitter-coupled logic circuit includes a differential pair, an output stage, and a compensation circuit. The differential pair is configured to receive a differential signal and is operative to generate a differential signal. The output stage is coupled to the differential pair to receive the differential signal and is operative to generate a differential output signal at a DC output voltage level. The compensation circuit is coupled to the differential pair and the output stage and is operative to develop a compensating voltage drop in the differential pair so as to compensate for a change in the DC output voltage level when the temperature varies such that the output stage outputs the differential output signal at the DC output voltage level.
