Abstract

Schaltungsanordnung zur Erzeugung eines Referenzpotentials mit einem ersten Transistor (T1), dessen Emitter mit einem Bezugspotential (M) verbunden ist und dessen Basis und Kollektor miteinander verschaltet sind,
mit einem zweiten Transistor (T2), dessen Basis mit der Basis des ersten Transistors (T1) verbunden ist,
mit einem ersten Widerstand (R1), der zwischen den Kollektor des ersten Transistors (T1) und einem Ausgangsanschluß (U) zum Abgreifen des Referenzpotentials geschaltet ist,
mit einem zweiten Widerstand (R2), der zwischen den Kollektor des zweiten Transistors (T2) und den Ausgangsanschluß (U) geschaltet ist,
mit einem dritten Widerstand (R3), der zwischen den Emitter des zweiten Transistors (T2) und das Bezugspotential (M) geschaltet ist,
mit einem dritten Transistor (T3), dessen Basis mit dem Kollektor des zweiten Transistors (T2) und dessen Emitter mit dem Bezugspotential (M) verbunden ist, und mit einer gesteuerten Stromquelle (T3, T4), die zwischen ein Versorgungspotential (V) und den Ausgangsanschluß (U) geschaltet ist und die eingangsseitig mit dem Kollektor des dritten Transistors (T3) gekoppelt ist und mit einer Kapazität (C1), die dem zweiten Widerstand (R2) parallel geschaltet ist.
