<p>A high frequency oscillator (1) is provided with a plurality of resonant circuits (2, 3); a plurality of amplifier circuits (4, 5) each of which is connected to each of the resonant circuits for outputting resonance signals; and a plurality of separate power supply voltage supply paths, which are branched toward the amplifier circuits (4, 5) from a common power supply voltage supply path connected to a power supply voltage input section (Vcc) and supply each of the amplifier circuits (4, 5) with a voltage based on the power supply voltage. A resistive circuit (R10) for voltage dividing is arranged on the common power supply voltage supply path. Resistive circuits (R3, R13) for voltage dividing are arranged on the paths which connect the separate power supply voltage supply paths with the ground, respectively. The divided voltage of the power supply voltage provided by the resistive circuits (R10, R3) for voltage dividing is applied to the amplifier circuit (4). The divided voltage of the power supply voltage provided by the resistive circuits (R10, R13) for voltage dividing is applied to the amplifier circuit (5).</p> |
