ABSTRACT
A fully digital self-adjusting high efficiency power supply
system has been developed based on an FSM control scheme.
The system dynamically monitors circuit performance with a
slacktime detector, and provides a substantially constant
minimum-supply voltage for digital processors to properly
operate at a given frequency with regard to different process-
voltage-temperature (PVT) and load conditions. The digital
FSM scheme significantly reduces the complexity of control
loop implementation (<1800 gates) and its own power
consumption (<100W).
1. INTRODUCTION
As semi-conductor process technology has become lower-
voltage and deeper sub-micron, and the number of transistors
