Abstract

Full-swing low voltage BiCMOS Schmitt trigger which ensures full logic amplitudes in two different ways is described. In this paper full-swing Schmitt trigger circuits have two complementary outputs: BiCMOS (inverting) and CMOS (noninverting). Proposed mathematical model to determine threshold voltages is verified by simulation. Voltage hysteresis depends on supply voltage, MOS transistor threshold voltages and geometry ratio of input MOS transistors and transistors within the positive feedback loop. As this ratio increases from 0.3 to 2, voltage hysteresis changes from 0.2VDD to 0.54VDD.
