Abstract

본 발명은 적응형 등화기를 공개한다. 디지탈 비디오 디스크 플레이어 또는 시디-롬 드라이버등과 같은 시스템의 RF 증폭단에 포함되며, 디스크의 배속에 상응하는 주파수를 제어 전압의 형태로 변환시켜 출력하는 넓은 주파수 도입 범위를 갖는 위상 동기 루프를 포함하는 시스템의 그 등화기는, 외부로부터의 제어 신호에 응답하여 제어 전압을 소정 범위로 조정하여 출력하는 전압 조정 수단 및 전압 조정 수단으로부터 출력되는 제어 전압의 소정 범위에 따라 제어 전류를 조정하고, 조정된 제어전류를 출력하는 전류 조정수단을 구비하고, 제어 전류에 반비례하여 부스트할 주파수를 조정하는 것을 특징으로 하고, 등화기와 넓은 주파수 도입 범위를 갖는 위상 동기 루프간의 제어 전압 미스매칭 제거하는 효과가 있다.The present invention discloses an adaptive equalizer. Included in the RF amplification stage of systems such as digital video disc players or CD-ROM drivers, the system includes a phase locked loop with a wide frequency introduction range for converting and outputting a frequency corresponding to the speed of the disc in the form of a control voltage. The equalizer of the controller adjusts the control current in accordance with a predetermined range of the control voltage output from the voltage adjusting means and the voltage adjusting means for adjusting and outputting the control voltage to a predetermined range in response to a control signal from the outside, and the adjusted control current. It is provided with a current adjusting means for outputting a, characterized in that for adjusting the frequency to boost in inverse proportion to the control current, there is an effect of eliminating the control voltage mismatch between the equalizer and the phase locked loop having a wide frequency introduction range.
