Abstract

Low-frequency double-resonance quartz crystal oscillator circuit was developed with active inductance aiming the quick start-up in the intermittent operation on the sensor circuit and DC isolation using a Q-MEMS sensing crystal HTS-206. Allan standard deviation indicated 5 × 10^–12, showing short range stability of the sensor circuit sufficient for the ubiquitous environmental sen sor network.
