Abstract
Various embodiments of the invention allow to cancel demodulation phase error. In certain embodiments, cancellation is accomplished by determining the phase delay of a drive front end signal that is in phase with an undesired signal and digitally adjusting the demodulation signal with a calibrated signal. The phase delay may be adaptively compensated during regular circuit operation, only at predetermined times, or during a factory calibration.
