ABSTRACT:
A d.c. high voltage operational amplifier. The output of a conventional power operational amplifier is converted to a.c. which is stepped up by a transformer and then rectified to provide a high voltage d.c. output. Appropriate feedback circuitry is utilized to stabilize the overall operational amplifier against oscillation and provide substantially perfect linearity between the input and output voltages of the high voltage operational amplifier when incorporating negative feedback.
