Wireless devices that can operate across a variety of standards continue to grow in importance, while innovations such as spectrum-sharing radios are on the verge of gaining broad acceptance. Therefore, low-cost radios that can operate over a wide range of standards and frequency bands are of great interest. This talk presents recent work on two complementary approaches: the first introduces a new technological component that employs phase-change materials to reconfigure RF circuits, while the second employs circuit techniques to enhance linearity over wide bandwidths.
Jeyanandh Paramesh received the B.Tech. degree from the Indian Institute of Technology, Madras, India, in 1996, the M.S. degree from Oregon State University, Corvallis, in 1998, and the Ph.D. degree at the University of Washington, Seattle in 2006, all in electrical engineering. He is currently Assistant Professor of Electrical and Computer Engineering at Carnegie Mellon University, Pittsburgh. He has held industrial positions in mixed-signal and RF circuit design at AKM Semiconductor (Analog Devices), and Motorola (Freescale). He has also been employed as a Graduate Student Researcher with the Communication Technology Laboratories, Intel Corporation. Dr. Paramesh was a recipient of the Chevron Engineering Scholarship (1997), the Intel Foundation Doctoral Fellowship (2003–2004), and the Analog Devices Outstanding Student Designer Award (2005).
