Talk Title: Multi-Order Harmonic Generation for Linear Oscillators and Wideband Frequency Synthesis

Abstract: It is presented the evolution of highly linear oscillators based first on Band-pass filter and multi-level comparators. Then by employing harmonic suppression or selective harmonic enhancement to yield besides linear oscillators, also wide frequency range and/or high frequency oscillators with frequency higher than its fundamental.
Secondly it is presented architectural solutions for the realization of wideband frequency synthesizers. First, we present a new architecture which uses two-step multi-order harmonic generation of a low frequency phase-locked signal to generate wideband mm-wave frequencies. Measurements of a prototype fabricated in 90nm CMOS technology show that using a phase-locked input signal of 1-1.43GHz, the system can provide an output which covers the frequency range of 5 – 32 GHz. This represents a tuning bandwidth of 27 GHz with a tuning range of 146%. The measured phase noise at 1 MHz offset is -116 dBc/Hz and -99 dBc/Hz at 5 GHz and 32 GHz, respectively.


Biography: Prof. Edgar Sánchez-Sinencio was born in Mexico City, Mexico. He received the degree in communications and electronic engineering (Professional degree) from the National Polytechnic Institute of Mexico, Mexico City, the M.S.E.E. degree from Stanford University, Stanford, CA, and the Ph.D. degree from the University of Illinois at Champaign-Urbana, in 1966, 1970, and 1973, respectively.
He has graduated 51 M.Sc. and 39 Ph.D. students. He is a co-author of six books on different topics, such as RF circuits, low-voltage low-power analog circuits, and neural networks. He is currently the TI J. Kilby Chair Professor and Director of the Analog and Mixed-Signal Center at Texas A&M University. His current interests are in the area of power management, ultra-low power analog circuits, data converters and medical electronics circuit design.
He is a former Editor-in-Chief of IEEE Transactions on Circuits and Systems II and a former IEEE CAS Vice President–Publications. In November 1995 he was awarded a Honoris Causa Doctorate by the National Institute for Astrophysics, Optics and Electronics, Mexico. This degree was the first honorary degree awarded for microelectronic circuit-design contributions. He is a co-recipient of the 1995 Guillemin-Cauer Award for his work on cellular networks. He received the Texas Senate Proclamation # 373 for Outstanding Accomplishments in 1996. He was also the co-recipient of the 1997 Darlington Award for his work on high-frequency filters. He received the IEEE Circuits and Systems Society Golden Jubilee Medal in 1999. He is the recipient of the prestigious IEEE Circuits and Systems Society 2008 Technical Achievement Award. He was the IEEE Circuits and Systems Society’s Representative to the IEEE Solid-State Circuits Society during 2000–2002. He was a member of the IEEE Solid-State Circuits Society Fellow Award Committee from 2002 to 2004. He is currently (2012-2013) a Distinguished Lecturer of the IEEE Circuit and Systems Society
