Base drive circuits provide high-impedance drive to the base contact region on whichever side of the device is (instantaneously) operating as the collector. (B-TRANs, unlike other bipolar junction transistors, are controlled by applied voltage, not applied current.) Control signals operate preferred drive circuits, providing diode-mode turn-on and pre-turnoff operation, and a hard ON state with a low voltage drop (the “transistor-ON” state). In some (not necessarily all) preferred embodiments, a self-synchronizing rectifier circuit provides an adjustable low voltage for the gate drive circuit. Also, in some preferred embodiments, the base drive voltage used to drive the c-base region (on the collector side) is varied while monitoring the base current at that terminal, so that no more base current than necessary is applied. This solves the difficult challenge of optimizing base drive in B-TRANs."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Operating point optimization with double-base-contact bidirectional bipolar junction transistor circuits, methods, and systems","description":"The present application teaches, inter alia, methods and circuits for operating B-TRANs (double-base bidirectional bipolar junction transistors).
