Modern commercial and military wireless systems should support various waveforms and standards under dynamically changing electromagnetic environments. A straight forward Software-Defined Radio (SDR) enables changing the radio parameters, such as carrier frequency, modulation format, and signal bandwidth, in a fixed architecture, through software. A more advanced reconfigurable radio enables changing the architecture of the transceiver and/or the individual building blocks in order to optimize the performance while minimizing the power consumption. Architectural level reconfigurability reduces the Non-Recurring Engineering (NRE) cost associated with the design of a new transceiver tailored to a specific application. Moreover, dynamic adjustment of radio architecture and specifications can be in response to, for instance, varying signal to noise ratio levels, locations and powers of interference and jamming signals, etc. This talk covers several examples of reconfigurable radio-frequency transceivers implemented in CMOS technology.
Philipp Häfliger received the M.Sc. degree in computer science (with astronomy as a second subject) from the Swiss Federal Institute of Technology (ETH), Zürich, Switzerland, and the PhD degree from the Institute of Neuroinformatics at ETH in 1995 and 2000, respectively. He then moved for a postdoctoral position to the Nanoelectronics Group at the Department of Informatics at the University of Oslo, Norway, where he has now advanced to Associate Professor and Section Leader. In Oslo, his research focus shifted gradually from neuromorphic (inspired by the nervous system) electronics towards ultra-low-power ASIC design for biomedical devices, in particular wireless microimplants, and more recently for micro-probes for space research. Dr. Häfliger has been Chairman of the IEEE Circuits and Systems (CAS) Society’s Biomedical and Life Science CAS (BioCAS) Technical Committee (2010–2012), and has served and still serves in various functions for the IEEE ISCAS and IEEE BioCAS conferences, and as associate editor for the IEEE Transactions on BioCAS.
