VOLTAGE CONTROL OSCILLATOR USING BULK ACOUSTIC WAVE RESONATOR AND FABRICATING METHOD THEREOF

摘要

PURPOSE: A voltage control oscillator using a bulk acoustic wave resonator and a fabricating method thereof are provided to improve a characteristic of a phase noise by using a heating portion for changing a resonant frequency according to a controlled voltage. CONSTITUTION: A voltage control oscillator using a bulk acoustic wave resonator includes a bulk acoustic wave resonator and an amplifier. The bulk acoustic wave resonator is used for controlling a resonant frequency according to a controlled voltage. The amplifier is used for generating an output signal of a particular frequency by amplifying a resonant frequency of the bulk acoustic wave resonator. The bulk acoustic wave resonator includes a heating coil(7) in order to change the resonant frequency according to a heating degree.
