OSCILLATOR CIRCUIT, METHOD FOR MANUFACTURING OSCILLATOR CIRCUIT, INERTIAL SENSOR USING THE OSCILLATOR CIRCUIT, AND ELECTRONIC DEVICE

摘要

An oscillator circuit is provided with an oscillator, a filter for filtering the monitor signal outputted from the oscillator to output the filtered signal, a drive part for amplifying the filtered signal outputted from the filter to generate a drive signal, and a control unit which operates in a manner so as to adjust the pass characteristic of the filter on the basis of the monitor signal. The oscillator is driven by the drive signal and oscillates, and outputs the monitor signal according to the oscillation. The oscillator circuit is able to stably oscillate an oscillator.
