Back. Thus, the circuit hysteresis loop is related to supply potential and device threshold values. Schmitt triggers on the basis of their hysteresis width and average power consumed. In electronics, a Schmitt trigger is a comparator circuit with hysteresis implemented by applying positive feedback to the noninverting input of a comparator or differential amplifier. 1. The problem lies in the discharge phase (low pulse width), which takes much longer than the charging phase (high pulse width). The trigger switches at different points for positive- and negative-going signals. Schmitt logic circuits are often used to design pulse generators. In this design, a dynamic body-bias is applied to a simple CMOS inverter circuit, whereby the threshold voltages of the two MOSFETs can be changed, thus changing the switching voltage.

This In Schmitt Trigger the input value can be analog or digital but the output will be in two forms 1 or 0. The advantage of an inverting Schmitt trigger is that it is also a hysteresis device, meaning that whatever signal is being outputted at the current moment has an effect on any future output.
