Abstract
A system and method for noise cancellation in a signal-processing circuit (e.g., an analog-to-digital converter circuit). Various aspects of the present invention may comprise inputting a first input signal and a digital input signal to the signal-processing circuit. The digital input signal may, for example, comprise a digital dither signal or other processor control signal. The signal-processing circuit may, for example, output a signal comprising a first signal component that is primarily a function of the first input signal and a second signal component that is primarily a function of the digital input signal. The second signal component may be estimated based on estimated behavior of the signal-processing circuit in response to the digital input signal. The estimated second signal component may, for example, be substantially removed from the signal-processing circuit output signal.
