The oscillator circuit 10 comprises a crystal oscillator 20, a transistor 30, whose base is connected to the crystal oscillator 10, a first resonance circuit 40 that is between the emitter of the transistor 30 and the ground, the first resonance circuit 40 having a first inductor 42 and a first capacitor 44, a second resonance circuit 50 that is between the emitter and the ground, the second resonance circuit 50 having a second inductor 52 and a second capacitor 54, and a third capacitor 60 that is between the base and the emitter. The first resonance frequency of the first resonance circuit 40 is higher than the overtone frequency of the main oscillation of the crystal oscillator 20, and the second resonance frequency of the second resonance circuit 50 is lower than the overtone frequency of main oscillation of the crystal oscillator 20. |
