Level shifter with boost and attenuation programming

A level shifter configured to generate an output voltage having a shifted voltage level relative to an input voltage, the level shifter comprising:

• a first gain module having a first resistance, the first gain module configured to generate a first voltage based on the input voltage and the first resistance;
• a load module having a second resistance, the load module configured to generate a second voltage based on the first voltage and the second resistance;
• a second gain module having a third resistance, the second gain module configured to adjust one of
• the second voltage based on the third resistance, or
• the first voltage based on the third resistance;
• an output driver configured to output the output voltage having the shifted voltage level based on the adjusted one of the first voltage and the second voltage,
• wherein the second gain module includes a programmable resistor configured to i) receive a gain control signal and ii) provide the third resistance;
• and
• a bias module configured to i) receive the gain control signal and ii) generate a bias current for the second gain module, wherein a value of the bias current affects an amount that the output voltage is shifted relative to the input voltage, and
• wherein the gain control signal is configured to i) adjust a resistance value of the programmable resistor and ii) adjust the value of the bias current.
