Class Information
Number: 257/918
Name: Active solid-state devices (e.g., transistors, solid-state diodes) > Light emitting regenerative switching device (e.g., light emitting scr) arrays, circuitry, etc.
Description: Subject matter wherein an active solid-state device acts as if it has two or more active emitter junctions each of which is associated with a separate, equivalent transistor having an individual gain and, when initiated by a base region* current, the equivalent transistors mutually drive each other in a regenerative manner to lower the voltage drop between the emitters, and which active solid-state device can generate light.
