ABSTRACT:
In one embodiment, an algorithm is employed to calibrate electronic circuitry that is adjustable according to operating parameters. The calibration causes an output component to be substantially nulled. The algorithm includes adjusting at least one of the operating parameters over a plurality of values, applying an input signal to the electronic circuitry concurrently with the adjusting, measuring magnitudes of the output component from the electronic circuitry produced in response to the input signal and the adjusting, wherein the plurality of values are selected such that the magnitudes are not substantially nulled, and providing the magnitudes and the plurality of values to a curve fitting algorithm to calculate a plurality of operating parameters that cause the output component to be substantially nulled.
