RESONATOR, PHASE-LOCKED LOOP, AND SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE |
| 摘要 |
A resonator is supplied with voltage from a constant-voltage source, and the constant-voltage source outputs output voltage adjusted by a voltage adjustment signal to the resonator. The resonator outputs a clock signal having a frequency varied by varying capacitance in accordance with a received control signal and a frequency adjustment signal, and a frequency of the clock signal is varied by voltage output from the constant-voltage source. |
