METHOD AND SYSTEM OF OPERATING A BI-DIRECTIONAL DOUBLE-BASE BIPOLAR JUNCTION TRANSISTOR (B-TRAN)

Last updated:

Abstract:

Operating a bi-directional double-base bipolar junction transistor (B-TRAN). One example is a method comprising: injecting charge carriers at a first rate into an upper base of the transistor, the injecting at the first rate results in current flow through the transistor from an upper collector-emitter to a lower collector-emitter, and the current flow results in first voltage drop measured across the upper collector-emitter and the lower collector-emitter; and then, within a predetermined period of time before the end of a first conduction period of the transistor, injecting charge carriers into the upper base at a second rate lower than the first rate, the injecting at the second rate results in second voltage drop measured across the upper collector-emitter and the lower collector-emitter, the second voltage drop higher than the first voltage drop; and then making the transistor non-conductive at the end of the conduction period.
