NDR Devices and their Digital Applications

Abstract

The objective of this project carried out under the ULTRA program of DARPA, was to validate the potential of ultrafast quantum-effect tunneling devices for the design of ultra-dense circuits and systems. The first part of the research effort involved the design, fabrication, and characterization of RTDs and HBTs. Information about device performance was then used to design and fabricate RTD-HBT circuits for a variety of unique low power high speed digital and analog applications. To facilitate the design and characterization of RTD-based circuits, a new simulator was developed that included physics-based device models for various tunneling devices as well as convergence routines to alleviate problems associated with the negative differential resistance characteristics of RTDs. The report also presents circuit and system design activities that sought to co-integrate RTDs and MOS devices to develop a viable circuit technology for the post-shrinking VLSI era.
