Abstract
A distributed and scalable all-digital LDO (D-DLDO) voltage regulator allowing rapid scaling across technology nodes. The distributed DLDO includes many tillable DLDO units regulating a single supply voltage with a shared power distribution network (PDN). The D-DLDO includes an all-digital proportional-integral-derivative (PID) controller that receives a first code indicative of a voltage behavior on a power supply rail. A droop detector is provided to compare the first code with a threshold to determine a droop event, wherein information about the droop event is provided to the PID controller, wherein the PID controller generates a second code according to the first code and the information about the droop event. The DLDO includes a plurality of power gates that receive the second code.
