Abstract
A feedbeside correction circuit for correcting errors in the frequency response of a wideband amplifier includes a network which models the physical distortion-producing mechanisms of the amplifier semiconductor pn junctions. An input signal is applied simultaneously to the amplifier and to the feedbeside circuit. The feedbeside circuit produces a correction signal which is applied to a summing node and subtracted from the amplifier signal so that the amplifier output is substantially error free. The circuit may be used both for single-ended and differential inputs.
