ABSTRACT:
A level shifter circuit comprises a bias module that receives a first signal and that selectively outputs a selected one of a second signal and a third signal based on an operating frequency of said level shifter circuit. A programmable gain module receives a gain control signal, and generates a fourth signal based on said gain control signal and said selected one of said second signal and said third signal. A bias generation module communicates with said programmable gain module, receives said gain control signal, and generates a bias for said level shifter circuit based on said gain control signal.
