Abstract

Optimum power gating sleep transistor design and implementation are critical to a successful low-power design. This paper describes important considerations for the sleep transistor design and implementation including header or footer switch selection, sleep transistor distribution choices and sleep transistor gate length, width and body bias optimization for area, leakage and efficiency. It also investigated various power-on current rush control methods for the sleep transistor implementation.
