Abstract
A low voltage CMOS differential amplifier is provided. More specifically, in one embodiment, a device comprising a differential pair is provided. A self-biased transistor and a component are coupled to the differential pair. At least one of the self-biased transistor and the component supply a current to the differential pair, wherein the component supplies substantially all of the current when the self-biased transistor is operating in a triode state.
