Abstract :
Novel full-swing BiCMOS/BiNMOS logic circuits using bootstrapping in the pull-up section for low supply voltage down to 1 V are reported. These circuit configurations use noncomplementary BiCMOS technology. Simulations have shown that they outperform other BiCMOS circuits at low supply voltage using 0.35 μm BiCMOS process. The delay and power dissipation of several NAND configurations have been compared. The new circuits offer delay reduction between 40 and 66% over CMOS in the range 1.2-3.3 V supply voltage. The minimum fanout at which the new circuits outperform CMOS gate is 5, which is lower than that of other gates particularly for sub-2.5 V operation
