Abstract
Method and system aspects for nulling output offset current in an amplifier are described. In an exemplary method aspect, the method includes determining at least one offset value with a power amplifier in at least one mode. The at least one offset value then utilized to identify an output offset current value in the power amplifier. An adjustment to an input signal to the power amplifier occurs until the output offset current value is substantially nulled to identify a power amplifier offset value.
