Abstract

A circuit for providing an output voltage to a pincushion modulator circuit. The circuit includes an amplifier having an input for receiving an input signal. The amplifier amplifies the input signal to produce the output voltage at an output of the amplifier which is coupled to an input of the pincushion modulator circuit. A compensation path eliminates instability at frequencies above a first frequency caused by interaction between the amplifier and the pincushion modulator circuit.
