The talk presents low-power design strategies for front-end circuits, such as PA, LNA, mixer, and VCO. The design strategies focus on not only the low energy consumption with reused bias current but also the small chip area for low spurious environment contamination. For the low-power design, some published literatures have been adopted the operation voltage from 3V down to only 0.2V, to save the dissipated dc power from tens mW to several hundreds of μW. Additionally, many design strategies and green figures of merit (GFOM) are also presented in this work, for the future green RF circuit design.

   Wu-Shiung Feng received the B.S.E.E., M.S.E.E., and Ph.D. degrees from National Taiwan University, Taipei, Taiwan, ROC, in 1970, 1974, and 1980, respectively. During 1974-1979, he was an Instructor at the Department of Electrical Engineering, National Taiwan University. During 1980 to 1985, he was an Associate Professor, as well as a Full Professor from 1986 to 1998. Since 1998 retired from National Taiwan University, he is a Chair of the Department of Electronic Engineering and a Director of Graduate Institute of Semiconductor Technology, Chang Gung University, Tao-Yuan, Taiwan, ROC. He was the dean of the College of Engineering,Chang Gung University from 2001 to 2004.
   From 1979 to 1980, he was a Visiting Scholar at Stanford University, Palo Alto, CA, where he spent one year in Solid-State Electronics Laboratory. From 1984 to 1985, he joined the IC design group at the Department of EECS, University of California, Berkeley, CA. His current research interests are VLSI layout, timing and integrity design, and wideband RF IC design. He has published over hundreds of technical papers. He was awarded the Best Technical Paper Award at the Chinese Institute of Engineers, Rep. of China, in 1981 and the Best Paper Award of Design Session, IMAPS Society, May 1998. He obtained the 2001 Academic Excellent Award of Chang Gung University. Dr. Feng is a Senior member of the IEEE Society and the Chinese Institute of Engineers.
