Abstract
The series stacked (SS) FinFET structure is used in digital low dropout (DLDO) regulators to withstand high input voltages and implement dynamic voltage scaling (DVS) technique with minimum energy point (MEP) technique. Through an additional delay consideration in MEP, both energy reduction and performance of the Cortex M0 processor can achieve 34.5pJ/cycle at 0.5V. Maximum energy reduction is about 37.5% and the supplying voltage varies from 0.4V to 0.775V with a search time of 2.5μs for each voltage step. The proposed SS-DLDO has fast settling time and low output voltage ripple of 1.5μs and 5mV, respectively.
