Title: Analog and Digital Phase-Locked Loops: A Full Day Tutorial
Place: École Polytechnique de Montréal, Lassonde Building (Pavillon Lassonde), 2nd Floor, Room M-2107.
Date and time: 17/10/2013, 9:00 am – 4:30 pm



Phase-locked loop (PLL) circuits are a key component of most modern communication circuits, and are also used in a variety of digital processor applications in order to generate high frequency, low jitter clock sources. This tutorial-level presentation will present an overview of analog and digital frequency synthesizers, including basic concepts and recent innovation.

The first half of the short course will be focused on providing key modeling and circuit concepts of analog and digital PLLs. Classical analog integer-N synthesizers will first be examined in order to provide background on basic PLL components, modeling, and system level tradeoffs.  Analog fractional-N synthesizers will then be presented along with the key principles of Delta-Sigma modulation. Discussion of digital frequency synthesizers will follow, with high performance time-to-digital conversion being a particular focus point.

  The second half of the short course will be focused on behavioral level simulation of phase-locked loops. A short demo of the CppSim program will be provided, which is free software that can be downloaded from www.cppsim.com. Following this demo, fast and accurate simulation techniques of PLLs will then be discussed and related to what is provided in the CppSim software package. After this discussion, each participant will be guided through exercises to better understand how to create models and perform simulations using this program.  As such, it is recommended that participants bring a Windows or Mac laptop (preferably with CppSim already installed) so that they can actively participate in this session.


Speaker Biography

Michael H. Perrott received the B.S. degree in Electrical Engineering from New Mexico State University, Las Cruces, NM in 1988, and the M.S. and Ph.D. degrees in Electrical Engineering and Computer Science from Massachusetts Institute of Technology in 1992 and 1997, respectively. From 1997 to 1998, he worked at Hewlett-Packard Laboratories in Palo Alto, CA, on high speed circuit techniques for Sigma-Delta synthesizers. In 1999, he was a visiting Assistant Professor at the Hong Kong University of Science and Technology. From 1999 to 2001, he worked at Silicon Laboratories in Austin, TX, and developed circuit and signal processing techniques to achieve high performance clock and data recovery circuits. He was an Assistant and then Associate Professor in Electrical Engineering and Computer Science at the Massachusetts Institute of Technology from 2001 to 2008. He was with SiTime Corporation from 2008 to 2010, where hedeveloped key technology for MEMS-based oscillators. He was a professor at Masdar Institute in Abu Dhabi from 2011 to 2013, where he focused on low power, mixed-signal circuits for health monitoring. He is currently at Silicon Laboratories in Nashua, New Hampshire.
