Wladek Grabinski received the Ph.D. degree from the Institute of Electron Technology, Warsaw, Poland, in 1991. From 1991 to 1998 he was a Research Assistant at the Integrated Systems Lab, ETH Zürich, Switzerland, supporting the CMOS and BiCMOS technology developments by electrical characterization of the processes and devices. From 1999 to 2000, he was with LEG, EPF Lausanne, and was engaged in the compact MOSFET model developments supporting numerical device simulation and parameter extraction. Later, he was a technical staff engineer at Motorola, and subsequently at Freescale Semiconductor, Geneva Modeling Center, Switzerland. He is now an consultant responsible for modeling, characterization and parameter extraction of MOS transistors for the design of RF CMOS circuits. He is currently consulting on the development of next-generation compact models for the nanoscaled technology very large scale integration (VLSI) circuit simulation. His current research interests are in high-frequency characterization, compact modeling and its Verilog-A standardization as well as device numerical simulations of MOSFETs for analog/RF low power IC applications. He is an editor of the reference modeling book Transistor Level Modeling for Analog/RF IC Design and also authored or coauthored more than 50 papers. Wladek is a member ESSDERC TPC Track4: ＂Device and circuit compact modeling＂ as well as is serving as a member of the IEEE EDS Compact Modeling Technical Committee, organization committee of ESSDERC/ESSDERC, TPC of SBMicro, SISPAD, MIXDES Conferences; reviewer of the IEEE TED, IEEE MWCL, IJNM, MEE, MEJ. He also contunited as European representative to the ITRS Modeling and Simulation working group. He was a Member At Large of Swiss IEEE ExCom and also mentored the EPFL IEEE Student Branch acting as its Interim Branch Counselor. Wladek is involved in activities of the MOS-AK Association and serves as a coordinating manager since 1999.
