    摘要： 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.

    摘要： A level shifter circuit includes a bias module that receives a first voltage value, that generates a second voltage value when an operational frequency of the level shifter circuit is less than a threshold, and that generates a third voltage value when the operational frequency is greater than or equal to the threshold. A programmable gain module generates a fourth voltage value based on the second voltage value when the operational frequency is less than the threshold and based on the third voltage value when the operational frequency is greater than or equal to the threshold. The bias module includes a load module that receives the first voltage value and that generates the second voltage value and a bypass module that receives the first voltage value and that generates the third voltage value. A gain value of the programmable gain module determines a voltage gain of the level shifter circuit.
