Title:  An Introduction to 802.11a/b/g/n/ac Radio Design : From Systems to Transistors

 

Abstract
A short lecture on the evolution of the 802.11 standard with an emphasis on the radio design will be presented. After a brief discussion of the market trends, the performance of the 802.11’s OFDM-based modulations as well as multi-in multi-out (MIMO) design in an multi-path environment will be outlined. The general evolution of the 802.11 PHY from b to a to g to n to ac is presented and the impact of these PHYs on the radio design is discussed. Further, the impacts of various radio impairments (noise, quadrature inaccuracy, nonlinearity, etc.) on the performance of the various PHYs will also be presented. Some specific examples of circuit techniques and architectures used in various 802.11n radios will be discussed. The evolution of 802.11 radio performance metrics throughout the past several years will be outlined. The lecture will wrap up with some real-world throughput measurement results and a brief discussion of the future trends of radio design.

Bio
Arya Behzad obtained his BSEE and MSEE from ASU and UC Berkeley in 1991 and 1994 respectively. After working for UTC, Microunity and Maxim, he joined Broadcom in 1988 where he is currently a Senior Director of Engineering working on radios and SoCs for current and future generation wireless products. He was designated as a Broadcom Distinguished Engineer in 2007 and as a Broadcom Fellow in 2009 for the design and productization contributions to CMOS RF transceivers and power amplifiers. He has published numerous papers and is an inventor on well over 100 issued patents in the areas of precision analog circuits, gigabit Ethernet, set-top boxes and wireless networking. He has taught courses and presented technical seminars at various conferences and at several universities. He is a retired member of the ISSCC Wireless Technical Committee as well as a retired Guest and Associate Editor of the JSSC. He has authored the book, “Wireless LAN Radios”, IEEE Press/Wiley. He is an IEEE Distinguished Lecturer as well as an IEEE Fellow.
