Abstract
Circuits and methods for reducing distortion in an amplified signal are disclosed. The circuits and methods may use multiple single-ended gain stages to produce multiple amplified signals. The amplified signals may be processed in combination to produce a resulting output signal having little, or no, distortion. The circuits may be implemented on a single chip as integrated circuits.
