Abstract
본 발명은 안정된 주파수를 발생하도록 하기 위한 제어장치를 구비한 전압제어발진기에 관한 것으로, 입력되는 제어전압에 따라 소정의 주파수를 발생하는 전압제어발진기; 상기 전압제어발진기의 주변 온도에 따라 소정의 제어신호를 발생하는 온도감지수단; 및 상기 온도감지수단에서 발생된 제어신호에 따라 VCO주변의 온도를 가변시키기 위한 온도가변수단을 포함함을 특징으로 한다.The present invention relates to a voltage controlled oscillator having a control device for generating a stable frequency, the voltage controlled oscillator for generating a predetermined frequency according to the input control voltage; Temperature sensing means for generating a predetermined control signal in accordance with the ambient temperature of the voltage controlled oscillator; And a temperature variable stage for varying a temperature around the VCO according to a control signal generated by the temperature sensing means.
본 발명에 의한 온도제어장치를 구비한 전압제어발진기에 의하면, 온도 변화에 매우 민감한 VCO 주파수 변화를 상당이 개선할 수 있으며, 적용하는 제품의 특성이나 서미스터의 온도특성에 따라 온도의 가변범위를 적절히 조절할 수 있다.According to the voltage controlled oscillator having the temperature control device according to the present invention, the VCO frequency change which is very sensitive to the temperature change can be significantly improved, and the variable temperature range of the thermistor may be appropriately adjusted according to the characteristics of the applied product or the temperature of the thermistor. I can regulate it.
