Wireless RF Transceivers and New Trends in Design

Ertan Zencir


Abstract: Over the past two decades, research in RF CMOS integrated circuits at universities and industry has made significant progress in architectural developments and enabling high performance RF/analog building blocks. This research, initiated in late 1980s, yielded fully-integrated very low power CMOS RF transceivers and systems-on-chip (SOC) solutions on par with their bipolar and BiCMOS counterparts in wireless markets.
In this seminar, present and the most popular transceiver architectures employed in wireless applications will be reviewed. Polar Transmitter and Software Defined Radio (SDR) Receiver will be discussed to draw conclusions on future research. As an example, a low-IF UHF SOI (Silicon on Insulator) CMOS receiver targeted for deep-space communications will be presented in details. Silicon On Insulator (SOI) CMOS technology, which made its first appearance in the semiconductor world in the late 1980s, has recently become a new technology of choice for digital and analog designers due to advantages over bulk CMOS such as high density deep-submicron capability, reduced junction capacitances, better integration density, increased device fT, lower minimum achievable noise figure and lower power dissipation. The design and measurement results of a standard CMOS power amplifier (prototyped for the UHF transmitter side) and a bandgap reference circuit realized under the same project will also be covered for more exposure to block level design. 

Dr. Ertan Zencir has received his Ph.D. in Electrical Engineering from Syracuse University in 2003. In August of 2004 he joined the Electrical Engineering and Computer Science Department of University of Wisconsin-Milwaukee (Milwaukee, WI) as an Assistant Professor. His industrial career as an RFIC researcher started in Nokia R&D’s RFIC group (San Diego, CA) in January 2005. During his period at Nokia, he was involved in the design of advanced low-power BiCMOS RF transceiver circuits for CDMA2000 cellular standard. Since April 2006, he has been a Staff Scientist in the RF and Analog Microelectronics Department of Broadcom Inc. (Irvine, CA) focusing on the design of high performance RF and analog circuits for satellite communications. He has 1 pending patent application and several publications in the area of RF CMOS integrated circuits.
