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.
