Abstract
A novel full swing BiCMOS Schmitt trigger, consisting of a BiCMOS inverter and a CMOS latch circuit, is proposed. This new circuit outperforms a conventional CMOS Schmitt trigger significantly. Even when the supply voltage is lowered down to 1.5 V, the new Schmitt trigger still maintains good operational quality. Based on the PSPICE simulations, the proposed BiCMOS circuit has less transmission delay and delay power product, as well as no static current under various supply voltages and output loads. The power consumption of the BiCMOS Schmitt trigger is actually slightly less than that of the CMOS counterpart. The circuit is also a full swing design. With these characteristics, this circuit is very suitable for high-speed and low-power applications
