Abstract

Die Erfindung bezieht sich auf eine Integratorschaltung mit einem kapazitiv rückgekoppelten Differenzverstärker (2) und mit einer Kapazität (C2), deren erste Elektrode über einen ersten Schalttransistor (S1) mit dem Schaltungsein­ gang (1) und über einen zweiten Schalttransistor (S3) mit dem invertierenden Verstärkereingang verbunden ist. An­ gestrebt wird, daß d)e Schaltung der bilinearen Über­ tragungsfunktion genügt. Erreicht wird dies dadurch, daß die zweite Elektrode der Kapazität (C2) über einen dritten, mit dem zweiten (S3) synchron betätigbaren Schalttransi­ stor (S2) mit dem Schaltungseingang (1) und über einen vierten mit dem ersten synchron betätigbaren Schalttransi­ stor (S4) mit dem nichtinvertierenden Verstärkereingang verbunden ist. Der Anwendungsbereich der Erfindung um­ faßt monolithisch integrierte Filterschaltungen.
