Performance Comparison of Driver Configurations and Full-Swing Techniques for BiCMOS Logic Circuits

Abstract

Driver configurations and full-swing techniques for several types of BiCMOS logic circuits have been compared among each other to examine their performance in scaled technologies. Among three driver configurations (common emitter, gated diode, and emitter follower) analyzed, the emitter-follower type is most advantageous for scaled power-supply voltage circuits. Also, full-swing techniques boost the circuit performance and base-emitter shunting is more favorable than collector-emitter shunting. © 1990 IEEE
