Oscillator

発振装置

Abstract

PROBLEM TO BE SOLVED: To solve a problem of a conventional oscillator through which a large amount of consumption currents flow because two currents for specifying two operations are separately and independently made to flow. SOLUTION: An oscillator includes: an oscillation circuit for generating an oscillation signal with an oscillation frequency and receiving supply of a first current required for the generation; and an amplifier circuit for a multiple signal with a multiple frequency being a multiple of the oscillation frequency and receiving supply of a second current required for the amplification, and at least parts of the first and second currents flow in common.
