A 115mV 300fW 0.24Hz 0.00012 $\text{mm}^{2}$ Schmitt-Trigger Ring Oscillator Using Dynamic Leakage Suppression with Cold Start Capability in 22nm CMOS
This paper presents a low-voltage, low-power, small-footprint ring oscillator circuit design. By utilizing dynamic leakage suppression technique associated with Schmitt-trigger topology, low-power under low-supply voltage becomes feasible. A prototype chip has been developed in 22nm CMOS, and its footprint is <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$0.00012 \mathbf{\ m m}^{2}$</tex>. Measurement results show the successful functionality with <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{1 2 5 m V}, 300 \text{fW}, 0.24 \ \text{Hz}$</tex>, and cold start up capability.
