Abstract
본 발명은 TV수상기의 오디오 FM 신호 처리회로와 관련된 것으로서, 이는 특히 종래 FM 신호처리의 복조처리단에서 신호의 위상 쉬프트와 전류 조절회로를 집적회로 구성할때 위상 쉬프트측에 연결되는 탱크회로가 두개의 단자핀을 점유할 수 밖에 없어 이러한 회로의 집적화에 불리하게 작용되는 문제를 야기하였으나, 본 발명에선 이러한 문제점을 개선할 수 있도록, 하나의 단자핀에 의한 탱크부(13) 접속이 가능토록 한 위상 쉬프트 스위치부(11)와, 전류미러형 전류원 출력부(12)를 포함한 구성의 TV 수상기에서 FM 신호처리회로를 제공하는데 있다.The present invention relates to an audio FM signal processing circuit of a TV receiver, which includes two tank circuits connected to a phase shift side when an integrated circuit is configured for a phase shift of a signal and a current control circuit in a demodulation stage of conventional FM signal processing. However, in order to solve this problem, in the present invention, it is possible to connect the tank 13 by one terminal pin. The present invention provides an FM signal processing circuit in a television receiver having a phase shift switch section 11 and a current mirror type current source output section 12.
