Abstract
Integratable circuit arrangement for delaying pulse-shaped signals. A differential amplifier circuit is composed of a first current source connected to a zero potential, of an emitter-coupled transistor pair and of two resistors. The two collectors of the transistor pair are respectively connected to the zero potential via a further current source and are connected to one another via a capacitor. A further transistor introduced into both collector lines of the transistor pair delays pulse-shaped signals that are applied at the bases of the transistor pair and the further transistor in a defined allocation to one another, delaying the signals as a function of the current flowing in the coupled emitters of the transistor pair and as a function of the voltage appearing across the capacitor.
