The field of RF design has exploded over the last 25 years. The insatiable appetite for “big data” using wireless technologies requires future RF transceivers to support much higher data rates with higher reliability and longer range. Increasing Wi-Fi speeds and the number of users is also pushing the backbone wireline communication data rates to higher limits. There is a strong drive towards a higher level of integration in all of the RF design areas from millimeter waves to wireless sensors. RF front-ends, frequency synthesizers, and baseband A/D and D/A converters along with digital front-end signal processing subsystems are being integrated on System-on-Chips (SoCs) in CMOS technology. In this seminar, we will review the key technology trends and drivers for RF/Analog CMOS Integrated Circuits. After a brief overview of RF fundamentals, we will discuss the challenges faced by RF IC designers due to CMOS process scaling and SoC integration. As enabling technology solutions, we will go through the high performance circuit design techniques in detail for a wideband Low Noise Amplifier (LNA) and a wideband Power Amplifier (PA).
Dr. Rajesh Zele is the Technical Director at MaxLinear, focused on developing the next generation CMOS RF and Mixed-Signal SoCs for Digital Cable and Satellite Gateways. Prior to MaxLinear, Dr. Zele served as the Vice President, R&D services of MindTree, leading the team for Bluetooth and short range wireless transceivers. He founded and served as Managing Director of Alereon Semiconductors to develop ultra-wideband RF ICs for Wireless USB products. Before Alereon, he was the Director of Engineering at Zilker labs developing power management Digital-DC products. He established Austin Design Center for the startup Free Electron Technology and managed the technical team responsible for 10Gbps optical networking products. Dr. Zele has extensive background in wireless transceivers at Motorola, where he was IC design manager for the Talk-About radio platform, now in high volume commercial production. He has presented talks at various IEEE conferences and symposiums. He has written over 20 papers, co-authored a book chapter and holds 8 US patents. Dr. Zele received Ph.D. in EE, from Carnegie Mellon University, MSEE from Oregon State University, and B.Tech. from Indian Institute of Technology, Bombay. He is the Senior Member of IEEE.
