  • Abstract
    An ultra-low power CMOS 90nm Reverse-Body-Bias generator is proposed to reduce digital circuit leakage. A Switched-Capacitor-Converter (SCC) and a Low-Drop-Out regulator generate Pwell and Nwell voltages, respectively. It can supply digital circuits up to 4mm2 while occupying 0.02mm2. Its nominal current consumption is 348nA. Pulse-train control provides wide output current range, and process and temperature compensation without sacrifying efficiency. The SCC achieves a best-in-class efficiency of 52% at 100nA load including the control loop.
