Abstract:
1. An oscillator circuit comprising: a resonance circuit formed of a resonator as an inductor component and dividing capacitors, each dividing capacitors having a first end connected to the resonator and a second end connected to ground, an oscillation amplifier driven by a power voltage connected to said resonance circuit, and a pull-down resistor provided between an output terminal of said oscillation amplifier and ground, wherein said pull-down resistor is serially-connected dividing resistors, the serially-connected dividing resistors being a first pull-down resistor connected circuit side and a second pull-down resistor connected ground side, and a by-pass capacitor is directly connected between a connection point between said dividing resistors and ground, wherein a resistance of the first pull-down resistor is less than a resistance of the second pull-down resistor.
