Performing low power refresh of a digital-to-analog converter circuit

Abstract:

In one embodiment, an apparatus includes: a digital-to-analog converter (DAC) circuit having a digital portion to receive a digital value and an analog portion to generate an analog voltage based on the digital value; and a refresh circuit coupled to the DAC circuit to clock gate provision of a first clock signal to the DAC circuit when the digital portion is inactive.
