OSCILLATION CIRCUIT, OSCILLATOR, ELECTRONIC DEVICE, MOVING OBJECT, AND MANUFACTURING METHOD OF OSCILLATOR

摘要

An oscillator circuit includes a circuit for oscillation, a temperature compensated circuit, an output circuit, and an amplitude control circuit. The output circuit outputs an oscillation signal as a signal output from the circuit for oscillation is input. The amplitude control circuit includes an amplitude control portion which controls amplitude of the oscillation signal output by the output circuit, and a heat generation portion into which a DC current is input and which generates heat. The heat generation portion controls the input DC current based on operation states of the circuit for oscillation and the amplitude control portion.
