Claim Text:
1. An oscillator circuit, comprising: a first resonator; a second resonator, having a frequency characteristic different from a frequency characteristic of the first resonator; a frequency adjusting unit, being configured to change a ratio between a contribution of the first resonator and a contribution of the second resonator so as to adjust an output frequency, wherein the frequency characteristic is a resonance frequency, the frequency adjusting unit includes: wherein the first adjusting unit includes a first transistor and a first variable resistor, the first transistor causing a flow of the first current, the first variable resistor being configured to adjust the first current value, and the second adjusting unit includes a second transistor and a second variable resistor, the second transistor causing a flow of the second current, the second variable resistor being configured to adjust the second current value.
