摘要： In various embodiments, systems and methods for generating high-precision pulse-width modulation include a delay-locked loop comprising multiple delay units having time-variable delays, control logic for selecting a subset S of the multiple delay units to thereby generate a time-invariant shift amount having a precision finer than that of a system clock and circuitry for applying the shift amount to rising and falling edges of a pulse-width modulation waveform to thereby generate a high-precision pulse-width modulation waveform.

摘要： A system for reducing power consumption in a transistor-based system includes a measurement circuit and a comparator. The measurement circuit measures a delay of a transistor-based device and produces a control signal corresponding to the measured delay. The comparator compares the control signal to a predetermined threshold. Adjusting a power supply voltage of the transistor-based system based at least in part on a result of the comparison reduces the power consumed by the system.
