Abstract

A wide common-mode range receiver includes an input module, voltage level shift module, voltage level shift control module, and output module. The receiver can also include an equalizer. The receiver translates data originating from a circuit powered from an external voltage supply to a circuit powered by an internal voltage supply. The voltage level shift may be scaled based on differences between the voltage supplies or by determining the difference between an input common-mode voltage and a reference voltage, and driving a servo based on the difference.
