Lucien Breems (S’97-M’00-SM’07) received the M.Sc. degree (cum laude) and the Ph.D. degree in Electrical Engineering from the Delft University of Technology, The Netherlands, in 1996 and 2001 respectively. From 2000 to 2007 he was with Philips Research, Eindhoven the Netherlands and in 2007 he joined NXP Semiconductors where he leads a team working on high-resolution A/D converters. Since 2008 he is a lecturer at the Delft University of Technology and in 2011 he became part-time professor at the Technical University of Eindhoven. His research interests are in the field of wireless receivers, data converters and mixed-signal circuit design. He is a member of the technical program committee of ESSCIRC and he has served in the TPCs of the ISSCC, the Symposium on VLSI Circuits and the IEEE International Symposium on Low Power Electronics and Design. In 2009-2014 he has been an Associate Editor of the IEEE Journal of Solid-Sate Circuits and he has served as Guest Editor of the IEEE Transactions on Circuits and Systems-II (2008-2009). He has been IEEE Distinguished Lecturer. He is recipient of the ISSCC “Van Vessem Outstanding Paper Award” in 2001 and 2011 and the IEEE Journal of Solid-State Circuits best paper award in 2011.



The application space of delta-sigma analog-to-digital converters has been greatly extended during the last few decades with applications ranging from traditional applications such as audio and hearing aids that require only a few (tens of) kHz bandwidth to a multitude of cellular standards that need up to 40MHz bandwidth. To enable this bandwidth range of four orders of magnitude, new innovative wideband delta-sigma architectures and circuits have been developed that operate at GHz rate sampling frequencies. This tutorial gives an introduction to the system design and implementation of wideband delta-sigma modulators. A review of wideband delta-sigma architectures, loop stability, filter implementations and circuit designs is presented. Some case studies illustrate wideband delta-sigma modulators that have bandwidths in the range from several tens of MHz to beyond 100MHz
