Schmitt Trigger Circuit Diagram and Schematic

A Schmitt trigger is a comparator circuit that incorporates positive feedback. The following schematic shows a typical diagram of Schmitt Trigger Circuit. This Schmitt trigger circuit is “emitter coupled” and provides a simple comparator action. When the input is higher than a certain chosen threshold, the output is high.

Cascode Video FET Amplifier Circuit Diagram using 2N3823

The following schematic shows the FET Amplifier Circuit Diagram application on Cascode Video. The FET cascode video amplifier features very low input loading and reduction of feedback to almost zero.
