Abstract: A level shifter circuit is configured to receive first and second complementary input signals. Each of the first and second complementary input signals have a value of either a first supply voltage or a first reference voltage. The level shifter further includes a strong latch circuit operable in response to the first and second complementary input signals to drive one of first and second output signals to a second supply voltage and includes a weak latch circuit operable to drive the other of the first and second output signals to a second reference voltage.

Abstract: An apparatus comprises a reference voltage bias generator configured to generate a first reference voltage and a second reference voltage. During a low supply mode, the first reference voltage is equal to a supply voltage potential and the second reference voltage is equal to a ground potential. During a high supply mode, the first reference voltage is equal to a first fraction times the supply voltage potential and the second reference voltage is equal to a second fraction times the supply voltage potential. The apparatus further includes a reference voltage booster coupled to the reference voltage bias generator, wherein the reference voltage booster is configured to generate the first reference voltage and the second reference voltage with increased drive capability.
