Abstract
Systems and methods for reducing the magnitude of signal dependent capacitance are provided. Capacitance canceling circuitry is operative to generate cancellation capacitance in response to the magnitude of a signal, which may be the same signal that produces the undesired signal dependent capacitance, to at least partially cancel the signal dependent capacitance.
