Deepnarayan Gupta

President, Digital-RF Circuits and Systems

Dr. Deepnarayan Gupta is the President of HYPRES’ largest business division, Digital-RF Circuits and Systems, which produces the Advanced Digital-RF Receiver (ADR) and develops the underlying superconductor integrated circuits and cryogenic system integration technology for a variety of current and future applications. Dr. Gupta’s work encompasses analog-to-digital and digital-to-analog converters (ADC’s and DAC’s), digital signal processors (DSP), multi-chip modules (MCM), and cryocooled systems incorporating heterogeneous electronic and photonic technology. Dr. Gupta has led the development of ADR systems, which represent the first product with high-speed superconductor digital and mixed-signal integrated circuits. Now in its fourth generation, ADRs are modular, multi-function systems that serve multiple radio-frequency applications from low frequency to above 100 GHz.

Dr. Gupta was instrumental in changing HYPRES’ business direction in 2000–2001 to focus on RF applications and small-scale digital-RF systems and creating a $100M multi-faceted program consisting of synergistic research and development (R&D) projects funded by a variety of government agencies and other sources. In addition to ADR, he initiated the development of new products, such as the Integrated Cryogenic Electronics Testbed (ICE-T) and Cryogenic Analog RF Module (CARM).

Prior to joining HYPRES in 1997, Dr. Gupta was a post-doctoral research affiliate at Stanford University, working on hybrid superconductor-semiconductor electronics, a theme that he has continued to develop into the hybrid-temperature heterogeneous-technology (HTHT) systems concept that combines the strengths of various warm and cold electronic and photonic technologies to solve difficult technical problems. The foundation for that was laid through his doctoral research at LLE (1990–1995) under the supervision of Prof. William Donaldson and Prof. Alan Kadin. His research involved the invention of an inductive opening switch built with high-temperature superconductor (HTS) thin films and triggered by short laser pulses. Initiated by a Link Foundation fellowship in 1992, this research attracted additional Department of Defense funding. He received the Frank J. Horton Fellowship from 1993–1995. He earned B. Tech. in Electronics and Electrical Communications Engineering from the Indian Institute of Technology, Kharagpur, India, in 1990. Dr. Gupta, a Fellow of the IEEE, is a coauthor of more than 60 articles and holds over 50 U.S. patents. He serves on the boards of the Applied Superconductivity Conference and the United States Committee for Superconductor Electronics. Dr. Gupta has been serving as the IEEE Electron Device Society representative on the IEEE Council on Superconductivity since 2009.
