N2 - We propose a low power battery voltage supervisory circuit for micro-scale sensor systems that provides power-on reset, brown-out detection, and recovery detection to prevent malfunction and battery damage. Ultra-low power is achieved using a 57pA, fast stabilizing two-stage voltage reference and an 81pA leakage-based oscillator and clocked comparator. The supervisor was fabricated in 180nm CMOS and integrated with a complete 1 mm 3 sensor system. It consumes 635pW at 3.6V supply voltage, which is an 850x reduction over the best prior work.
