Biography
Dr. Chew Kok Wai, Johnny has been awarded the B.E.(Hons.) degree in electrical engineering, the M.Eng. degree and the Ph.D. degree in electrical engineering all from Nanyang Technological University, Singapore, in 1996, 1999 and 2007 respectively. In 1998, he joined Chartered Semiconductor Manufacturing as an Engineer in Mixed-Signal/RFCMOS Technology Development group where he was involved in Mixed-Signal process characterization and integration, RFCMOS device layout and characterization. In 2002, he became a Senior Engineer and joined the Spice Modeling group, where he has been responsible for RFCMOS and SiGe BiCMOS actives and passives testchip design, characterization, modeling and customer support across all technologies till the present day. He is currently holding the position of Member of Technical Staff and Group Leader for RFCMOS characterization and modeling. His research interests include characterization and modeling of RF MOS/bipolar transistors, RF passives and noise characterization and modeling of MOS transistors. He has published more than 15 articles in leading technical journals and conferences worldwide, and holds 18 US patents.
