Abstract:
A circuit for compensating asymmetry in a waveform of an input signal using a piecewise approximation of a saturation curve, the circuit including a first circuit configured to output a first compensation for a first section of the saturation curve using a first function and a second circuit configured to output a second compensation for a second section of the saturation curve using a second function. The second function is different than the first function. The first compensation and the second compensation provide the piecewise approximation of a region of the saturation curve. The region includes at least the first second and the second section.
