THE TUNNEL JUNCTION NEURISTOR.
Abstract
One of the components potentially useful in microelectronics systems is the neuristor, a distributed active transmission line having pulse propagation properties similar to those of a nerve fiber. The current status of the Naval Ordnance Laboratory's attempts to realize a practical neuristor device by employing a novel tunnel diode structure is contained in this report. Attempts at neuristor realization are reviewed and the basis is described for the approach based upon tunnel diode structures. The experimental results obtained on a variety of the latter devices are included, along with a discussion of some improved methods of trigger-coupled network realization. Propagation velocities on the order of 10,000 meters per second were measured over path lengths as great as 0.4 inches. Possible propagation mechanisms are discussed. The operation of a trigger junction was demonstrated but attempts to demonstrate a unilateral junction were inconclusive. Coupling of pulses between different lines via the substrate was also encountered along with a phenomenon having implications as a possible inhibit mechanism for refractory junctions. (Author)
