| titleOfInvention | DC level introducing device and phase locked loop combining this device |
| abstract | (57) Abstract: A self-oscillation frequency of a voltage-controlled oscillator of a phase-locked loop is automatically adjusted without external adjustment, and the phase-locked loop operates more stably. SOLUTION: A phase detector 10 and a first low pass filter 2 0, the second low-pass filter 60, the third low-pass filter 80, the amplifier 90, the voltage / current converter 7 which inputs the output voltage from the second low-pass filter and converts it into a constant current for output. 0, the output of the amplifier 90 and the buffer enable signal (BUF (EN) is input, and includes a DC level introducing device 100 that outputs a voltage selection signal and a voltage controlled oscillation voltage, a switch means 50 that performs voltage selection, and a voltage controlled oscillator 40, and cancels changes in parameters such as capacitance. The control DC voltage value is changed in the direction to automatically restore the predetermined self-oscillation frequency. |
