Low-leakage current, low-area voltage regulator for system-on-a-chip processors

A low-leakage current, low-area voltage regulator for system-on-a-chip processors is proposed. The system is demonstrated in a 0.13 µm CMOS technology with a supply voltage varied between 0.8 and 1.5 V. Using this system, the leakage current and power are reduced by as much as 44× and 33×, respectively, compared to conventional topologies.
