Join us for an IEEE Distinguished Lecture by Prof. Salvatore Levantino , Politecnico di Milano, Italy on Tuesday, 28 August 2018, 4:00 PM in Tyndall National Institute, Cork
Prof. Salvatore Levantino will present “Wideband Linear Phase/Frequency Modulators in CMOS”
A phase-locked loop can enable the direct frequency- or phase-modulation of the carrier for a variety of different applications: from polar RF transmitters to chirp generators for FMCW radars. Unfortunately, PLLs suffer from limited bandwidth and linearity of modulation. This talk will review the main techniques allowing for fast and tightly linear modulation, such as the pre-emphasis technique, two-point injection, and digital pre-distortion. Finally, two practical implementations of phase/frequency modulators in CMOS will be illustrated: a 3.6-GHz phase modulator capable of 20Mb/s GMSK/QPSK modulation with 5-mW power consumption, and a 20-GHz chirp generator with 1ms period and less than 200ns idle time.
Salvatore Levantino is Associate Professor of Electrical Engineering at Politecnico di Milano, Milan, Italy. His research includes wireless transceivers, frequency synthesizers, and data converters. Author of more than 100 papers on IEEE journals and conferences and the book “Integrated Frequency Synthesizers for Wireless Systems” published by CUP in 2007. He was guest editor for JSSC, associate editor for TCAS-I and TCAS-II, and co-recipient of the best paper award at the 2018 ISCAS conference. He is a member of the TPC for the IEEE RFIC Symposium.
