Abstract
An amplifier system is disclosed having improved distortion reduction. This system includes a DC voltage source having AC and DC components. An input signal to be amplified is supplied to an amplifier coupled to a DC voltage source for amplifying the input signal to provide an output signal in accordance therewith. Correction signal circuitry is provided including circuitry for separating the AC and DC components and varying the magnitude and phase of the AC component independently of the DC component to provide an adjusted AC component. The DC component and the adjusted AC component are summed together to provide an adjusted correction signal which is then combined with the input signal prior to application of the input signal to the amplifier.
