Design considerations and basic analysis for Inductors and CMOS Radio Frequency Integrated Circuits

Mr. Dror Regev – Terra Freedom Consulting
Dates: May 3,4 2011

Location: Meyer building, Auditorium floor 10

Department of electrical engineering, Technion, Haifa, Israel

This course will start with the design considerations and performance of RFIC inductors and continue with principles, strategies, topologies and challenges in basic CMOS RF circuit design. Simple but powerful analytical tools will be presented to allow designers a better understanding of the challenges and tradeoffs in circuit design preceding CAD circuit simulations. Approaches and tools employed in the seminar may be used as a basis for advanced analysis and design of other RFIC circuits.

Short biography

Dror Regev received the BsC degree in electrical engineering from Ben-Gurion University, Israel, in 1987, and the MsC. degree in management from Boston University, in 1994. He is currently teaching CMOS RFIC Circuit Design as an invited lecturer in the Department of Electrical and Computer Engineering, Ben-Gurion University, Israel. From 2006 he teaches RFIC design classes he authored to engineers in the Israeli wireless industry. He is member of IEEE Solid-State Circuits Society.
In 2007, he established an RFIC consulting firm and focused for 3 years on starting up Elipse RFIC Array Devices the first Israeli RFIC design house in Kfar Neter, Israel.
Prior to that, Mr. Regev was with Tower Semiconductors, Israel; Acer Labs, San Jose CA; Intel Haifa, Intel Kiriat Gat; Sierra Microwave Technology, Austin Texas and Elta systems, Israel in senior R&D and Engineering management positions.
