Self-biased feedback-controlled pull-down emitter follower for high-speed low-power bipolar logic circuits

In high-performance bipolar/BiCMOS digital VLSI chips, basic circuits such as Emitter-Coupled Logic (ECL), Non-Threshold Logic (NTL), and memories need to be fast while consuming little power. In this paper, a novel, self-biased, feedback-controlled, active-pull-emitter follower that is simple and efficient, needs only one signal, allows the collector-dotting and emitter-dotting, and yet demonstrates a far superior performance is presented.
