Abstract
본 발명은 주파수 합성기를 공개한다. 그 장치는 입력 주파수신호를 소정수로 분배하기 위한 제1분배수단, 상기 제1분배수단의 출력신호와 출력 주파수신호를 상기 소정수와 다른 수로 분배된 신호의 주파수 또는 위상차를 검출하기 위한 위상 비교수단, 상기 위상 분배수단에 의해서 검출된 주파수차 또는 위상차를 적분해서 직류전압을 출력하기 위한 저역통과 필터, 상기 직류전압에 의해 상기 출력 주파수신호를 가변하기 위한 전압 제어발진기, 및 상기 전압 제어 발진기의 출력 주파수신호를 상기 소정수와 다른 수로 분배하여 상기 위상 위상 비교수단으로 출력하기 위한 제2분배수단으로 구성되어 있다. 따라서, 입력 주파수신호를 소수배로 체배할 수 있다.The present invention discloses a frequency synthesizer. The apparatus comprises a first distribution means for distributing an input frequency signal by a predetermined number, and a phase comparison for detecting the frequency or phase difference of the signal distributed by the output signal and the output frequency signal of the first distribution means by a number different from the predetermined number. Means, a low pass filter for outputting a DC voltage by integrating the frequency difference or phase difference detected by the phase distribution means, a voltage controlled oscillator for varying the output frequency signal by the DC voltage, and the voltage controlled oscillator And second distribution means for distributing an output frequency signal in a number different from the predetermined number and outputting the same to the phase phase comparison means. Therefore, the input frequency signal can be multiplied by a factor of two.
