A 1.5 V full-swing BiCMOS logic circuit

A full-swing BiCMOS logic circuit is described which operates twice as fast as CMOS, even at 1.5 V supply. Transient-saturation of bipolar junction transistors (BJTs) enables high-speed operation below 2 V. This BiCMOS circuit is based on the concept of saturating the BJTs only when they drive the load, enabling full-swing operation without speed degradation. The configuration of the proposed BiCMOS circuit is shown, and simulation results are presented.<
