Abstract
본 발명은 전류제어 발진기(CCO : Current Controlled Oscillator)에 관한 것으로, 특히 전류제어단자로 전류원을 제어하여 차동증폭기의 저항에 흐르는 전류를 변환시켜 그 차동증폭기의 두 출력단에 서로 다른 전위인 고전위와 저전위를 각기 출력하여 발진하도록 한 전류제어발진기에 관한 것이다. 따라서, 본 발명은 전류제어단자가 전류원을 제어하여 차동증폭기의 저항에 흐르는 전류를 변화시켜 그 차동증폭기의 두 출력단에 서로 다른 전위인 고전위 신호 및 저전위 신호를 발생시키고, 이와같이 출력되는 두 신호를 다음단의 차동증폭기에 입력받아 순차로 차동증폭한후 처음단의 차동증폭기에 입력시켜 차동증폭하는것에 의해 발진신호를 발생시키므로, 고주파용 및 저전압용으로 사용되는 클럭발생과 고주파 소오스로 이용되고, 피엘엘 회로의 원칩화를 가능하게 하는 효과가 있다.In particular, the present invention relates to a current controlled oscillator (CCO). More particularly, the present invention relates to a current controlled oscillator (CCO), in which a current source is controlled by a current control terminal to convert a current flowing in a resistance of a differential amplifier, And outputting an electric potential to oscillate the current control oscillator. Therefore, in the present invention, the current control terminal controls the current source to change the current flowing in the resistance of the differential amplifier to generate the high-potential signal and the low-potential signal having different potentials at the two output terminals of the differential amplifier, Are input to the differential amplifier of the next stage and are sequentially amplified by differential amplification, and then input to the differential amplifier of the first stage to perform differential amplification to generate an oscillation signal. Thus, the oscillation signal is used as a clock generation and high frequency source used for high frequency and low voltage , It is possible to make one-chip of the PLL circuit.
