Abstract :
We propose a dynamic voltage boosting (DVB) method for improving performance by slightly boosting voltage within a withstand voltage. We measured an improvement of 44%voltage drop with about 10 % area overhead in a 65 nm CMOS. This DVB method combined with a series power gating can be used to achieve high performance for low-cost low-power SoCs in advanced process technology.
