Description

전병렬 A/D 변환기의 단위 비교회로Unit comparison circuit of all parallel A / D converter

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

제 1도는 종래의 전병렬 A/D 변환기에서의 단위 비교회로도. 제 2도는 본발멸의 전병렬 A/D 변환기에서의 단위 비교회로도.1 is a unit comparison circuit diagram of a conventional all-parallel A / D converter. 2 is a unit comparison circuit diagram of the main parallel A / D converter.

Claims (1)

단위비교기를 포함하여 이루어진 전병렬 A/D 변환기에 있어서, 단위비교기내의 래칭비교동작을 하는 트랜지스터(Q8,Q9)에 각각 연결된 저항(R2,R3)과의 사이에 캐스코드인 트랜지스터(Q14,Q15)를 각각 접속하고, 트랜지스터(Q14,Q15)의 각 콜렉터에서 포지티브 피이드백되는 신호는 레벨시프터인 트랜지스터(Q4,Q6), (Q5,Q7)를 통해 트랜지스터(Q8,Q9)의 각 베이스에 인가되게 접속함을 특징으로 하는 전병렬 A/D 변환기의 단위비교회로.In a all-parallel A / D converter including a unit comparator, a transistor having a cascode between resistors R 2 and R 3 connected to transistors Q 8 and Q 9 performing latching comparison operation in the unit comparator ( Q 14 and Q 15 are connected respectively, and the signal fed positively from each collector of transistors Q 14 and Q 15 is transferred through the transistors Q 4 and Q 6 and Q 5 and Q 7 which are level shifters. A unit comparator of an all-parallel A / D converter characterized by being connected to each base of a transistor (Q 8 , Q 9 ). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
