Abstract

본 발명은 신호의 최대값 검출방법 및 회로에 관한 것으로서, 입력신호의 초기값 및 최대값을 저장하는 래치; 상기 래치에 저장된 값과 새로운 입력값을 지속적으로 비교하는 비교기; 그리고 상기 래치의 새로운 입력값을 보존하는 버퍼;를 포함한 것을 그 특징으로 하여, 최대값의 검출 속도가 높아질 뿐만 아니라 마이크로프로세서의 부하를 경감시킬 수 있다.The present invention relates to a method and circuit for detecting a maximum value of a signal, comprising: a latch for storing an initial value and a maximum value of an input signal; A comparator for continuously comparing a value stored in the latch with a new input value; And a buffer to hold a new input value of the latch. In addition, the detection speed of the maximum value is increased and the load of the microprocessor can be reduced.
