Abstract

Ein temperaturstabilisierter Oszillator-Schaltkreis (1) umfasst einen ersten Teil mit einer ersten Temperaturabhängigkeit und einen zweiten Teil mit einer zu der ersten Temperaturabhängigkeit unterschiedlichen zweiten Temperaturabhängigkeit. Jeweils in einem der beiden Teile sind ein Ladungsspeicher (C2), eine steuerbare Aufintegrations-Stromquelle (T2) zum Laden des Ladungsspeichers (C2), eine steuerbare Abintegrations-Stromquelle (TB3) zum Entladen des Ladungsspeichers (C2) und zwei Widerstände (R2, R1), welche die gleichen Temperaturkoeffizienten aufweisen, enthalten.
