Abstract
A transmission line equalizer includes multiple signal paths connected in parallel between an equalizer input signal and an output amplifier where each signal path has a network implementing a specific frequency dependent response and each signal path implements current gain amplification with one or more of the signal paths having a variable gain programmed through a time invariant, DC programming signal. Furthermore, one or more of the signal paths implements linear-to-nonlinear signal transformations and compensating nonlinear-to-linear signal transformations to generate linearized output signals at the one or more signal paths. The equalizer further includes the output amplifier summing output signals from the multiple signal paths to generate an equalized output signal. In operation, the gain of the one or more signal paths is varied to establish the relative proportions of the output signals generated by each signal path and summed at the output amplifier.
