Abstract

Apparatus, method and article of manufacture are shown for linear signal modification. An input signal is modified by providing one or more non-linear current sources and regulating at least one of the one or more current sources to output a signal based on one or more of the input signal characteristics. The modification of the output signal includes both amplification and attenuation.
