ABSTRACT:
A new integrated circuit in which bias currents are supplied by means of a current injector, a multi-layer structure in which current is supplied, by means of injection and collection of charge carriers via rectifying junctions, to zones to be biased of circuit elements of the circuit, preferably in the form of charge carriers which are collected by the zones to be biased themselves from one of the layers of the current injector. By means of said current injector circuit arrangements can be realized without load resistors being necessary, while the wiring pattern may be very simple and the packing density of the circuit elements may be very high. In addition a simple method of manufacturing with comparatively few operations can in many cases be used in particular upon application of transistors having a structure which is inverted relative to the conventional structure.
