Description

히스테리시스 특성을 갖는 콤퍼레이터Comparator with hysteresis characteristics

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제2도는 본 발명에 의한 콤퍼레이터 및 그의 입출력 파형도.2 is a comparator and input / output waveform diagram thereof according to the present invention.

Claims (1)

차동증폭기 및 그의 액티브 로드인 커런트미러를 포함하여 구성되는 통상의 콤퍼레이터에 있어서, 트랜지스터 Q6 및 Q7을 차동증폭기로 구성하고, 그의 에미터에 바이어스 전류를 연결하며, 상기 차동 증폭기를 구성하고 있는 트랜지스터 (Q6)의 베이스를 Vref단자에 접속하고 트랜지스터(Q7)의 베이스를 VOUT단자에 접속하며, 상기 차동 증폭기의 콜렉터를 초단의 차동 증폭기(Q1', Q2')의 액티브 로드인 커런트미러의 에미터 및 저항(R')에 각각 연결하여 이루어진 것을 특징으로 하는 콤퍼레이터.In a conventional comparator comprising a differential amplifier and a current mirror which is an active load thereof, transistors Q6 and Q7 are constituted by a differential amplifier, and a bias current is applied to the emitter thereof. Connect the base of the transistor Q6 constituting the differential amplifier to the Vref terminal, the base of the transistor Q7 to the V OUT terminal, and connect the collector of the differential amplifier to the differential amplifier Q1 'of the first stage. And a resistor (R ') of the current mirror, which is an active load of Q2'). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
