Schmitt Trigger is a Bi-stable Multivibrator and its output remains in either of the two stable states i.e. +Vsat or -Vsat
The circuit gives +Vsat when the non-inverting input is greater than the inverting input.
The circuit gives -Vsat when the inverting input is greater than the non-inverting input.
As the output oscillates between the two states, the Schmitt trigger always generates a square wave.
Working of Schmitt trigger
When Vref > Vin, the output is +VCC
When Vref < Vin, the output is -VEE
The reference voltage is either VUT or VLT.
Upper threshold voltage
Lower threshold voltage
