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.
