Abstract
A CMOS Schmitt trigger which has two series-connected inverters uses both an input and an output signal to provide hysteresis. A pair of series-coupled transistors is coupled between a power supply terminal and a node between the two inverters. One of the transistors has a control electrode for receiving the input signal. The other of the transistors has a control electrode for receiving the output signal.
