Abstract

A 32-bit CPU which operates with the lowest energy of 13.4 pJ/cycle at 0.35V and 14MHz, operates at 0.22V to 1.2V and with 0.14μA sleep current is demonstrated. The low power performance is attained by Reverse-Body-Bias- Assisted 65nm SOTB CMOS (Silicon On Thin Buried oxide) technology. The CPU can operate more than 100 years with 610mAH Li battery.
