Abstract
A circuit for minimizing voltage excursions on the emitter-follower output terminals of an emitter coupled logic (ECL) gate including a compensating circuit connected to collector nodes associated with the input switching transistors and the reference switching transistor. The compensating circuit comprises a single current source for continuously delivering current which is selectively applied in predetermined amounts to one of the collector nodes residing in a high state. This predetermined amount of current compensates for undesired voltage changes experienced at the load impedance connected to that node due to varying ambient temperatures effecting the base-emitter junction of the output emitter follower transistor.
