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.

Abstract: Circuits and methods that improve the performance of voltage reference driver circuits and associated analog to digital converters are provided. A voltage reference driver circuit that maintains a substantially constant output voltage when a load current is modulated by an input signal is provided. The voltage reference driver circuit synchronously decouples a voltage regulation circuit from the load circuit when modulating events such as pulses caused by the load circuit during a switching interval are generated, preventing disturbance of the regulation circuitry and keeping its output voltage substantially constant.

Abstract: Circuits and methods that improve the performance of electronic circuits and associated analog to digital converters are provided. An electronic circuit that maintains a substantially constant output voltage to a load when receiving a substantially constant input voltage is provided. The electronic circuit includes a voltage booster isolation circuit coupled to a voltage regulation and a buffer circuit which selectively disconnects the buffer circuit from the voltage regulation circuit at or before the occurrence of a pulse induced by the load and which is further configured to provide a boosted bias voltage to the buffer circuit during a switching interval.
