Abstract: In a method and apparatus for digital-to-analog signal conversion, each of a plurality of first capacitors is charged during a first time period in accordance with an associated data bit of an input data byte. During a second time period that follows the first time period, the first capacitors are connected to a second capacitor for charge redistribution. During a third time period that follows the second time period, the second capacitor is connected to an operational amplifier to generate an analog output corresponding to the input data byte.

Abstract: In a method and system for low-distortion power amplification, an error signal is generated by comparing a feedback signal obtained from an amplified output signal of a power switching stage with one of an input pulse-width modulated (PWM) signal from a PWM signal generator and a corrected PWM signal at an input terminal of the power switching stage. Each pulse of the input PWM signal is then corrected to result in the corrected PWM signal that is provided to the power switching stage. Each pulse of the input PWM signal is corrected by adjusting the phase thereof such that each pulse of the input PWM signal has a center that forms a predetermined time difference with a center of a corresponding pulse of the corrected PWM signal, and by adjusting the width thereof according to the error signal.
