A Survey of Tunnel-Diode Digital Techniques

The tunnel diode, because of its high switching speed, wide environmental tolerance, and adaptability to digital computing circuits, has attracted much attention in the digital computer field. Efforts have been devoted to its application in both memory and logic circuits. Results have been most promising in high-speed random-access memories and in dynamic logic systems utilizing multiphase clock sources. This paper discusses the major techniques that have been reported plus some that have been developed by the authors and their associates at Bendix Research Laboratories.
