Level shifter with boost and attenuation programming

A level shifter circuit, comprising:

• biasing means for generating a bias voltage that receives a first voltage value, that generates a second voltage value when an operational frequency of said level shifter circuit is less than a threshold, and that generates a third voltage value when said operational frequency is greater than or equal to said threshold;
• gain programming means for programming a gain of said level shifter circuit that communicates with said biasing means, that receives a gain control signal, and that generates a fourth voltage value based on said second voltage value when said operational frequency is less than said threshold and based on said third voltage value when said operational frequency is greater than or equal to said threshold, wherein said fourth voltage value is based in part on said gain control signal;
• and
• bias generating means for generating a bias current for said level shifter circuit based in part on said gain control signal that communicates with said gain programming means.

A method for operating a level shifter circuit, comprising:

• receiving a first voltage value;
• generating a bias current for said level shifter circuit based on a gain control signal;
• generating a second voltage value when an operational frequency of said level shifter circuit is less than a threshold;
• generating a third voltage value when said operational frequency is greater than or equal to said threshold;
• generating a fourth voltage value based on said second voltage value and said bias current when said operational frequency is less than said threshold;
• and
• generating said fourth voltage value based on said third voltage value and said bias current when said operational frequency is greater than or equal to said threshold.
