Hermann Schumacher Professor Institute of Electron Devices and Circuits University of Ulm Impulse Radio UWB Circuits and Systems for Medical Applications When the US Federal Communications Commission opened up a frequency band from 3.1 to 10.6 GHz for unlicensed use with low spectral power density, it triggered a flurry of academic and industrial activity. For several years, most of the activities concentrated on wideband OFDM systems intended for ultra-highspeed wireless LAN applications. With the demise of the WiMedia consortium in 2009, attention refocused on impulse radio techniques, which have been shown to be an ideal candidate for high precision location, movement detection, and also low-power sensor node networks. Impulse radio UWB systems are well suited for applications in a biomedical context, such as vital sign detection or catheter tracking. The Ulm University group has been actively researching impulse radio circuits since 2004. The presentation will introduce their highly compact transmitter designs, as well as both correlation and energy detection receiver concepts, along with results of biomedical validation experiments. Biography Hermann Schumacher was born in Siegen, Germany, in 1957. He received his Diplom‐Ingenieur and Doktor‐Ingenieur degrees in Electrical Engineering from RWTH Aachen, Aachen, Germany in 1982 and 1986, respectively. In 1986, Dr. Schumacher joined Bell Communications Research (Bellcore), in Red Bank, NJ, as a member of technical staff, working on InP‐based optoelectronic and electronic devices. In 1990, he accepted a position at the University of Ulm as a professor in the Department of Electron Devices and Circuits. Here, his group works on Silicon and III‐V based heterostructure semiconductor devices and their applications in micro‐ and millimeter‐wave ICs. He was a visiting scholar at University of Wales in 1991, Bellcore in 1996, and Oregon State University in 1997. Since 1998, he has been the director of the Communications Technology International Master Program at the University of Ulm and received the State Teaching Award 1999 for his efforts in international education. From 2000 to 2003, he served as the University of Ulmʹs Vice President for Research, and served as a member of the Academic Senate from 2006 to 2010. Professor Schumacher was the co‐chair of the 2007 European Microwave IC conference (EUMIC 2007), chaired the RF Microsystems Cluster Meeting, the European Commissionʹs annual joint evaluation event for projects related to high‐frequency microsystems, in 2006 and 2008. and served as Technical Program Committee Chair for SiRF 2010 (New Orleans, LA). _______________________________________________ Colloquium mailing list [email protected] https://secure.engr.oregonstate.edu/mailman/listinfo/colloquium
