Abstract

New full-swing BiCMOS differential logic circuits called differential cross-coupled bootstrapped BiCMOS (DC²B-BiCMOS) and differential cross-coupled BiCMOS (DC²-BiCMOS) are proposed and analyzed. HSPICE simulations results show that as compared to bootstrapped BiCMOS CPL logic gate, the new DC²B-BiCMOS three-input XOR/XNOR gate with 1.5 V supply voltage and 0.5 pF output loading has about 80% and 86% improvement in the propagation delay and power-delay product, respectively, in 0.8 μm technology. Moreover, the DC²-BiCMOS with 0.5 pF output loading at 2 V offers about a 57% improvement in the propagation delay time over the Pass Transistor BiCMOS (PT-BiCMOS) differential logic gate
