Oscillator

Abstract

An oscillator includes: a vibrator having a first electrode and a second electrode disposed with a gap with the first electrode; a reference voltage supply circuit adapted to supply a reference voltage; and a voltage adjustment circuit having a step-up circuit operating in response to input of clock pulses and adapted to convert the reference voltage into a voltage of a predetermined level and to output the voltage of the predetermined level, wherein the vibrator is configured so as to apply the voltage of the predetermined level, which is output from the voltage adjustment circuit, between the first electrode and the second electrode, and the clock pulses to be input into the step-up circuit are obtained using the vibrator as a source.
