An ultra-low voltage digitally controlled low-dropout regulator with digital background calibration

In this paper, we describe a novel ultra-low voltage digitally controlled low-dropout (LDO) voltage regulator offering digitally controllable dynamic voltage scaling (DVS) for near/sub-threshold applications. We eliminate the reference voltage in conventional LDOs and adopt the reference clock that enables the proposed LDO to be controlled digitally. The… CONTINUE READING
