Abstract

Es ist eine Subtrahiererschaltung (1) angegeben, die an einem Ausgang (OUT2) ein zu einer am Eingang (2, 3) anliegenden Differenz (UD) zweier Signalpegel proportionales Signal liefert. Am Ausgang eines Operationsverstärkers (4) der Subtrahiererschaltung (1) sind zwei gleichlaufende Signalquellen (OUT1, OUT2) gebildet, von denen eine (OUT1) zur Rückführung von einem der beiden gleichartigen Ausgänge auf einen Eingang (5) des Operationsverstärkers (4) dient. Gemäß dem vorgeschlagenen Prinzip wird ein Rückführungswiderstand vermieden, der in analogen Subtrahiererschaltungen normalerweise vorhanden ist. Der veränderte Spannungshub am Ausgang des Operationsverstärkers (4) ermöglicht es, diesen ohne negative Versorgungsspannung betreiben zu können. Die beschriebene Subtrahiererschaltung (1) ist insbesondere zur Leistungsdetektion mit eingangsseitigem Leistungsdetektor (11) geeignet.
