Abstract
Embodiments of a method for amplifier calibration and an amplifier system are described. In one embodiment, a method for amplifier calibration involves amplifying an input signal using a first amplifier connected between an input terminal and an output terminal to generate an output signal and digitally performing offset calibration on a second amplifier coupled in parallel with the first amplifier between the input terminal and the output terminal while amplifying the input signal using the first amplifier. Other embodiments are also described.
