Patent ID: 6930537

Claim:
A band-gap reference circuit with averaged current mirror offsets, comprising: a differential amplifier circuit comprising a first input node operable to receive a first input signal, a second input node operable to receive a second input signal, and an output node operable to generate an output signal based on the input signal difference; a low current transistor circuit coupled to the differential amplifier circuit and operable to receive the output signal and to generate the first input signal based on the output signal; a high current transistor circuit coupled to the differential amplifier circuit and operable to receive the output signal and to generate the second input signal based on the output signal; and a configuration circuit coupled to the low current transistor circuit and to the high current transistor circuit, the configuration circuit operable to configure the band-gap reference circuit for a plurality of states by switching a plurality of components between the low current transistor circuit and the high current transistor circuit at specified intervals.
