JFET-Bipolar Cascode Circuit Diagram The following schematic shows the JFET- . The JFET- 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 problems with the 2N4091 JFET, thus allowing direct drive from the video detector. An m derived filter using stray capacitance and a variable inductor prevents 4.5 MHz sound frequency from being amplified by the video amplifier.
