    • For a piezoelectric oscillator according to the present invention, an oscillator circuit includes: a piezoelectric vibrator; an NMOS transistor and a PMOS transistor that constitute an amplifier connected in parallel to the piezoelectric vibrator; and load capacitors connected in parallel to the piezoelectric vibrator. The gate terminals of the NMOS transistor and the PMOS transistor, which are constituents of the amplifier, are connected by a DC cut capacitor, and the gate terminal of the NMOS transistor and the output terminal of the amplifier are connected by a feedback resistor. An arbitrary bias voltage, to be applied to the gate terminal of the PMOS transistor via a high-frequency elimination resistor, is generated by a circuit provided by a diode-connected, second PMOS transistor.
