PHB.32584 26.1.78 ABSTRACT OF THE DISCLOSURE: An integrated injection logic circuit comprising one or more threshold logic gates having a plurality of weighted logic inputs and a weighted fixed input determining the threshold. A threshold gate is formed by first and second transistors connected as a bistable, the state of which is determined in accordance with the difference in magnitude of total bias current supplied to the base of the first transistor and total bias current supplied to the base of the second transistor The threshold gate has associated current injector structures for supplying bias currents to the transistor bases, of which injector structures some are associated with logic inputs to the gate and when activated can supply bias current of a magnitude in accordance with the desired weighting of the input and at least one of said injector structures being associated with a fixed input which serves to determine directly or indirectly the desired threshold weighting of the gate. Positively or negatively weighted logic inputs may be present and positively or negatively weighted thresholds are readily obtainable. For obtaining continuous decision of the logic gate with suitable adjustment of current levels a current normalising connections present in each of the first and second transistors and comprises a connected between the transistor base and all additional collector zone. Figure 6 is suitable for publication purposes.
