Abstract

Accurate modeling of passive components and passive component ensembles is a critical step in high-speed design. In this talk, we will discuss some of the recent enhancements in our full-wave 3D electromagnetic simulator EMX. We discuss the various simulation and design issues that arise in the modeling of passive structures, such as, handling density dependent effects at sub 40nm nodes, simulation of 60GHz circuitry, modeling of thru-silicon-vias and the creation of scalable models for components. EMX is being used for simulation and modeling of a wide class of passive circuits including spiral inductors, MIM/MOM capacitors, Baluns, Filters, VCOs and RF Blocks and circuit ensembles. Several designs, fabricated on a variety of process technologies ranging from 0.25um to 28nm CMOS, SiGe and high-resistivity substrates, will be presented with comparisons to measurement.

Speaker Biography

Dr. Sharad Kapur is the president and co-founder of Integrand Software, Inc. He graduated with a Ph.D. in Computer Science (Numerical Analysis) from Yale University in 1996. He joined Bell Labs in 1996 as a member of technical staff. While at the design automation group at Bell Labs he co-developed several large software packages and tools, for electromagnetic analysis, circuit simulation and chip-level extraction. In 2003 he co-founded Integrand Software, Inc and helped develop the EMX 3D EM simulator. He is the author of over 30 peer-reviewed publications, primarily in the area of numerical analysis and electronic design automation. He is the holder of 6 US patents.
