ABSTRACT:
An object is not only to contribute to reduction in current consumption but also to advance actuation of a system required in a camera, an on-vehicle electric component, etc. by shortening a waiting time for stabilization of oscillation. An oscillator having an inverting amplifier inverting and amplifying an input signal and outputting it, a resonator connected to between an input and an output terminals of the inverting amplifier, a feedback resistance connected in parallel to the resonator, and an output circuit outputting a first clock signal based on a signal of an on-load parallel resonance frequency or a parallel resonance frequency oscillated by the resonator, the inverting amplifier and the feedback resistance to a function block is provided.
