ABSTRACT:
A charge coupled device that includes an input portion having an injection transistor and one or more partitioning transistors disposed in the potential well channel. The bases of the transistors are common. The collector of the injection transistor is common with the potential well channel. The total area of the base emitter junction of the partitioning transistor is larger in a certain predetermined relationship to the area of the base emitter junction of the injection transistor. An input signal of a larger than suitable value may be applied to the emitters and the current entering the collector of the injection transistor represents a predetermined fraction of the applied signal as a function of the relative areas of the base emitter junctions.
