Electronic Schmitt Trigger with Programmable Hysteresis Circuit Diagram. In electronics world, a Schmitt trigger is a comparator schema with hysteresis, implemented by applying positive feedback to the non inverting input of a comparator.

Electronic Schmitt Trigger with Programmable Hysteresis Circuit Diagram CA 3088 is used as a versatile Schmitt trigger. The size of the hysteresis levels is determined by Ia that flows out of the amplifier`s output and through R2. Increasing Ia increases hysteresis and vice versa. The positive and negative hysteresis levels are symmetrical about 0 V.
