Abstract:
This work presents an area-efficient voltage and frequency scalable clock generator for low-power digital SoC clocking. Named Direct Digital Sampling and Synthesis (DDSS), the open-loop generator implemented in 28 nm FD-SOI operates from 0.45 V to 1.1V with measured jitter from 1.7% to 5.1% UI. Its low power consumption of 0.40pJ/cycle at 57 MHz 0.5 V combined with the ability to perform fast frequency changes makes this circuit an alternative to PLLs for fast Dynamic Voltage and Frequency Scaling (DVFS) strategies in low power SoCs.
