Abstract
Bias controllers are provided which alter a bias control signal so that a bias signal (e.g., a current signal) of an electronic network rapidly responds to increases in the rate-of-change of the network's analog input signal. This enhances the linearity of a system that includes the electronic network. Subsequent decreases in the rate-of-change are sensed and a decrease of the bias control signal is then paced at a rate selected to ignore short-term rate-of-change variations (e.g., modulation variations) but follow longer-term rate-of-change reductions to thereby enhance system efficiency without sacrificing system linearity.
