Presentation: WMA-1: Improving Power-RF Performance Using a Comprehensive, Application-Oriented Approach to Modeling, Simulation, and Characterization
Speaker: Zul Mokhti
Date: Monday June 12 8:00 - 11:50
Abstract: Meeting the power, efficiency and linearity requirements of modern-day RF systems continues to become ever more challenging. In particular, GaN devices offer unique advantages and thus are becoming ubiquitous in high-power RF systems. However, they also present challenges with regard to transient response and linearization that complicate both device and circuit design. In this presentation we discuss a comprehensive approach to RF device, circuit and component design. We have realized improved results and shorter development cycle time by utilizing a rigorous approach including physical modeling, compact modeling, and behavioral modeling from the device level up to the system level. We see improved accuracy in design and simulation by using test signals that better represent real life situations. Industry standard test signals are used in conjunction with transient-capable behavioral models for both system level characterization and simulation of devices and circuits. By utilizing a more comprehensive and application-oriented approach, we can realize more accurate simulations during design and reduce the overall design cycle time.
Presentation: IWTU6: GaN–on–SiC: From Technology to System Design through Systematic and Accurate Modeling of Device Building Blocks
Speaker: Yueying Liu
Date: Tuesday, June 13 13:30-15:10
Location: 29D
Abstract: There are challenges in dealing with device behaviors at different design levels- from device physics to application specifics and system level interactions. In this workshop, an overview of the Wolfspeed design process, from technologies to systems will be presented. From material to technology, and the final product; each development step involves simulation analysis to understand the design parameter interactions impacts on systems. The design process usually involves trade-offs in order to achieve the optimum performance. Strategically choosing the right design tools and modeling strategy is the key to unlocking the superior quality of the technology.
