A 425pW, 0.3V, 32kHz Crystal Oscillator in 22nm FDSOI with Adaptive Pulse Injection and Amplitude Regulation Across −40°C to 125°C
This paper presents a sub-nW, single-supply crystal oscillator (XO) based on pulse injection at fundamental frequency. The integrated ZVD-based adaptive slicer enables accurate pulse injection timing against PVT variations at 162pW. The discrete PWA-based amplitude regulation enables oscillation amplitude regulation, reducing driver power to 93pW. The 22nm test chip shows a 3.7ppb Allan deviation floor at 425pW and <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$0.016\ \text{mm}^{2}$</tex>, with an operating temperature range from <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$-40^{\circ} \mathrm{C}$</tex> to 125° C.
