4 results about "Adaptive voltage scaling" patented technology

The application belongs to the technical field of low power consumption, and particularly relates to a low power consumption design method and device with adaptive voltage regulation. The method comprises the following steps: 1) simulating a key path of an analog-digital circuit, wherein the key path refers to a path with the maximum delay in the digital circuit; 2) generating a test clock signal and a sampling clock signal, and inputting the generated test clock signal into the key path; 3) detecting the output signal of the key path by using the sampling clock signal with the same sampling time and / or different sampling times, and controlling and adjusting the power supply voltage of the digital circuit according to the detection result, so as to determine the minimum power consumption voltage for ensuring the normal operation of the digital circuit. The application uses the key path to represent a complex load, and has simple structure and wide application range. The power supply voltage of the circuit is controlled and adjusted according to the voltage detection result, so that the control precision and the adjustment efficiency are improved, the minimum voltage for ensuring the normal operation of the circuit is determined, and energy saving is achieved.

A system may include one or more receivers, circuitry, and a controller. Each of the one or more receivers may include a plurality of analog-to-digital converters (ADCs). Each ADC may measure a time relating to an analog-to-digital conversion by the ADC, compare the time with a threshold, and generate, based on a result of the comparing, a first signal. The circuitry may be coupled to the one or more receivers. The circuitry may receive the first signal from each ADC, determine, based at least on the first signal, characteristics of performance of each receiver, and output a plurality of second signals. Each of the plurality of second signals may indicate the characteristics of performance of a corresponding receiver. The controller may be coupled to the circuitry and adjust a voltage provided to the one or more receivers, based at least on the plurality of second signals received from the circuitry.
