A 1.92驴s-wake-up time thick-gate-oxide power switch technique for ultra low-power single-chip mobile processors

摘要

A technique for controlling rush current and wake-up time of thick-gate-oxide power switches is described. Suppressing the variation of rush current on PVT allows shorter wake-up times, which can reduce leakage currents in a mobile processor. Wake-up takes 1.92驴s and leakage current is reduced by 96.9% in an application CPU domain. Probing the rush current indicated accurate control by the technique.
