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: A power supply is described. The power supply includes a synchronous sampled comparator. The synchronous sampled comparator includes a first input that receives a reference voltage. The synchronous sampled comparator also includes a second input that receives a feedback signal. The power supply also includes power field effect transistors (FETs). The power supply further includes an inductor coupled to the power FETs and coupled to the second input. The power FETs generate a power supply voltage using the inductor. The power supply voltage is a direct current (DC) power supply voltage.
