Claims (4)

Patentansprüche:
1. Einfache Gleichstromverstärkerschaltung mit zwei Transistoren vom komplementären Leitfähigkeitstyp, dadurch gekennzeichnet, daß der Emitter eines Transistors (1) des pnp-Typs, dessen Basis-Kollektor-Strecke die Eingangsspannung (Ue) zugeführt wird, mit der Basis eines Transistors (2) des npn-Typs, an dessen Kollektor-Emitter-Strecke die Ausgangsspannung (Ua) abgenommen wird, verbunden ist, daß der Emitter des ersten und der Kollektor des zweiten Transistors über je einen ohmschen Widerstand (3, 4) an positivem Potential liegt und daß der mit dem Emitter des zweiten Transistors (2) verbundene Kollektor des ersten Transistors (1) auf negativem oder Nullpotential liegt.
2. Gleichstromverstärkerschaltung nach Anspruch 1, dadurch gekennzeichnet, daß das Verhältnis der ohmschen Widerstände (3, 4) gleich der Stromverstärkung des zweiten Transistors (2) ist.
3. Gleichstromverstärkerschaltung nach den Ansprüchen 1 und 2, dadurch gekennzeichnet, daß eine Diode (S) vorgesehen ist, deren Kathode mit dem Kollektor und deren Anode mit der Basis des ersten Transistors (1) verbunden ist.
4. Gleichstromverstärkerschaltung nach Anspruch 3, dadurch gekennzeichnet, daß eine zweite Diode antiparallel zur ersten Diode (5) geschaltet ist.
