ABSTRACT:
In a lateral transistor structure, an auxiliary collector is interposed between the emitter and the main collector for controlling the flow of injected current carriers to the main collector. Alternatively, the main collector may be utilized for sensing the state of saturation of the interposed auxiliary collector. One or both of the main and auxiliary collector structures may be segmented to provide various function. In the case where only the auxiliary collector is segmented, the output on the main collector is proportional to the number of auxiliary collector segments biased to allow the injected current to pass to the main collector. Alternatively, a plurality of auxiliary collectors may be interposed in with the injected current series between the emitter and the main collector to provide an output at the main collector only if each and every one of the auxiliary collectors is biased for gating of current therethrough to the main collector. Such a device is particularly useful as an AND gate. An equivalent SCR structure that can be turned off is formed by providing positive feedback from the main collector to the base of the transistor. A saturation controlled transistor is obtained at the auxiliary collector output by providing negative feedback from the main collector to the base.
