Abstract: | A novel BiCMOS logic circuit is described that provides highspeed rail-to-rail operation with only one battery cell (1-1.5 V). The proposed circuit utilises a novel pull-down scheme that involves bootstrapping the base of the pull-down p-n-p bipolar junction transistor to a negative potential during the pull-down transient period. Circuit simulations have shown that the proposed circuit outperforms the transient-saturation full-swing BiCMOS and the bootstrapped bipolar circuits in terms of delay, power and cross-over capacitance for all simulated supply voltages |
