Abstract (en)

[origin: DE19621110C1] The circuit has a first transistor coupled to a given potential at its emitter and a second transistor coupled in common base configuration with the first transistor. The collectors of both transistors are coupled to the output terminal for the reference potential via respective resistors. The emitter of the second transistor is coupled to the given potential via a further resistor, its collector coupled to the base of a third transistor connected at its collector to a controlled current source. The switching signal is fed to the base of a fifth transistor in parallel with the third transistor.
