Abstract:
An oscillation circuit includes a temperature compensating section to which electric power is supplied from a main power supply and a backup power supply, an oscillating section, a function of which is compensated by a signal from the temperature compensating section, and a switch and a power-supply monitoring circuit configured to select, when the temperature compensating section is not operating, at least one of the main power supply and the backup power supply and control connection to the temperature compensating section.
