Abstract :
This paper presents a multi-story power delivery scheme which shows significant reduction of supply noise and power consumption compared to conventional power delivery scheme. To maximize the effectiveness of the proposed scheme, a digital voltage regulator is designed to balance the current dissipation of circuits in different voltage domains. Data transfer circuits based on capacitive coupling are developed for efficient inter-story data communication. Simulation results show 66% and 67% reduction of IR noise and Ldi/dt noise, respectively, while the total power consumption was reduced by 5% compared to a conventional power delivery scheme.
