摘要： A multichannel digital pulse width modulator/digital pulse frequency modulator uses a single ring oscillator that is shared by multiple channels. The ring oscillator has taps that can be used for least significant bit (LSB) precision of the generated PWM signal. The ring oscillator also produces a ring clock that is used to synchronize logic in the channels. Since the logic in the channels are synchronized by the ring clock, the channels can each independently produce different frequency PWM (or PFM) signals and still share the same ring oscillator.

摘要： Embodiments of the present invention concern a multiphase switch-mode power supply. The multiple phase switch-mode power supply can have at least one switch and a digital controller to control the switching of the at least one switch. During a calibration period, the digital controller can freeze the current of all of the multiple phases except for a phase being calibrated. This can be done by fixing the current reference of the phases except for the phase being calibrated.

摘要： In embodiments, a new analog-to-digital converter (ADC) architecture can be used with switch-mode power supplies (SMPS) operating at switching frequencies higher than 10 MHz. Analog-to-digital converter embodiments can achieve very low power consumption, fast conversion time, and can be implemented with a simple hardware. Another noteworthy benefit is that certain ADC embodiments feature a non-linear gain characteristic that provides improved load transient response for digital controllers.

摘要： A practical method and system for oversampled digitally controlled DC-DC converters is presented. To minimize the switching losses while maintaining all advantages of the oversampling, “glue logic” and application specific oversampling digital pulse-width modulator are introduced. Experimental results demonstrate transient response with 50% smaller deviation than that of conventional controllers, allowing for proportional reduction in the size of the power stage output capacitor.
