Abstract:
    A voltage control oscillator that is provided to suitably receive digital broadcasting and is produced at low costs includes: a resonance circuit that includes variable capacitors, each having a capacitance controlling terminal, that are provided parallel to each other and are connected to an inductor, the circuit resonating at a resonant frequency that varies depending upon a sum of (i) an inductance of the inductor and (ii) capacitances of the variable capacitors; and at least one switch to determine what should be connected to at least one of said capacitance controlling terminals.
