Abstract

A circuit for shifting an input common mode voltage is described. The circuit comprises a first current path configured to generate a first current between a reference voltage and a ground potential, the first current path having a first output; a second current path configured to generate a second current between the reference voltage and the ground potential, the second current path having a second output; a first bias current control circuit coupled to the first current path and the second current path, wherein the first bias control circuit is configured to receive the input voltage to control the current in the first current path and the second current path; and a second bias current control circuit coupled to the first current path and the second current path, wherein the second bias control circuit is configured to receive the input voltage to control the current in the first current path and the second current path. A method of shifting an input common mode voltage is also described.
