JFET-Bipolar Cascode

Posted on Feb 7, 2014

The following schematic shows the JFET- Bipolar Cascode Circuit Diagram. The JFET- Bipolar cascode circuit will provide full video output for the CRT cathode drive. Gain is about 90. The cascode is a two-stage amplifier composed of a transconductance amplifier followed by a current buffer. The cascode configuration eliminates Miller capacitance p
