Abstract: Exemplary embodiments are related to generating an error correction voltage and/or a compensation voltage based upon pulse-width modulation information. A device may include a pulse-width modulator configured to receive a first input voltage and convey a modulated output voltage. The device may also include a filtering unit including at least one filter configured to receive the modulated output voltage, generate at least one of an error correction voltage and a compensation voltage, and convey a second input voltage to the pulse-width modulator based on at least one of the error correction voltage and a compensation voltage.

Abstract: Certain aspects of the present disclosure provide an apparatus for noise cancellation. One example apparatus generally includes a first delay path and a second delay path, each providing signals generated by applying a different delay to an input signal, and a first comparator having a first input coupled to the first delay path and a second input coupled to the second delay path. The apparatus also includes a switching circuit having a control input coupled to an output of the first comparator, the switching circuit configured to selectively couple the first delay path or the second delay path to an output node of the switching circuit based on a signal at the control input. The apparatus also includes an attenuation circuit having a first input coupled to an input path for providing the input signal, and a second input coupled to the output node of the switching circuit.
