Abstract

Abstract Translated from German Eine integrierte Schaltungsanordnung zur Überwachung eines mit­integrierten Oszillators, der, über ein externes Frequenznormal angeregt, den für die Funktion der integrierten Schaltung syn­chron steuernden Takt liefert, enthält einen mitintegrierten Reserve-Oszillator, dessen Maximalfrequenz unter der Minimalfre­quenz des Oszillators liegt und einen mitintegrierten Frequenz­vergleicher, der die Frequenz des Reserve Oszillators mit der Frequenz des Oszillators vergleicht. An integrated circuit arrangement for monitoring a co-integrated oscillator, which, excited by an external frequency standard, supplies the clock synchronously controlling the function of the integrated circuit, contains a co-integrated reserve oscillator, the maximum frequency of which is below the minimum frequency of the oscillator, and a co-integrated frequency comparator, the compares the frequency of the reserve oscillator with the frequency of the oscillator.
