Abstract
A system including a first circuit and a second circuit. The first circuit is configured to (i) select a first portion of a signal based on a first offset, (ii) amplify the first portion of the signal according to a first function, and (iii) scale the amplified first portion based on a first factor to generate a first compensation for asymmetry in the first portion of the signal. The second circuit is configured to (i) select a second portion of the signal based on a second offset, (ii) amplify the second portion according to a second function, and (iii) scale the amplified second portion based on a second factor to generate a second compensation for asymmetry in the second portion of the signal.
