In-situ Timing Monitor based Adaptive Voltage Scaling System for Wide-Voltage-Range Applications


Privacy-Assured Outsourcing of
Abstract


In recent years, wide-voltage-operating-range circuit has drawn great attention, because of its ad-hoc performance and energy efficiency to meet various demands of different applications. It can either obtain the best possible energy efficiency at low voltage, or achieve high performance at nominal voltage. A big challenge is the severe Process, Voltage and Temperature (PVT) variations under nanometer process. Thus, when working at near-threshold region, it may result in timing failure and fails to achieve the possible high energy efficiency. In this paper, an Adaptive Voltage Scaling (AVS) method based on in-suit timing monitor is proposed with tunable detection window. It resolves the above problem by monitoring paths‚?? timing and adjusts the supply voltage adaptively. It is applied on a system-on-chip circuit consisted of a CPU, ESRAM, an AES cryptographic circuit and peripherals. Fabricated using SMIC 40nm CMOS process, it can work at 0.6V to 1.1V with remarkable power savings. Simulation results show that in the super-threshold voltage region, the supply voltage can be reduced from 1.1V to 0.86V, enabling a maximum of 50% power saving at FF corner, -25‚?? as compared to conventional non-AVS design. In the near-threshold region, the supply voltage is reduced to 0.48V, with a power saving up to 70% at FF corner, 125‚?? as compared to non-AVS design.
