Agenda and speakers

 

  • Impact of parasitic and EMI filter inductances on system-level ESD protection in high-speed data lines                                       

This presentation will provide a broad overview on how specific inductances improve system-level ESD robustness in high-speed data lines. Those inductances are either intrinsic PCB parasitics of microstrip lines or added to the system via EMI filters, i.e. Common Mode Chokes (CMC). The influence of the relatively small parasitic inductances <10nH is analyzed by mixed-mode TCAD-device simulation. Furthermore, the system ESD impact of different CMC inductances ranging from 30nH to 100uH for filters with and without ferrites are analyzed by TLP, vf-TLP, and ESD measurements. The presented results are relevant for different high-speed applications such as USB4.x, HDMI2.0, and automotive multi-Gigabit Ethernet.

  • Pitfalls of TLP, VF-TLP and HMM for ultra-high-current analysis of ESD discretes

​​​​​​​In this presentation the author will introduce briefly the advantages of the Transmission Line Pulse (TLP) generator for the characterization of semiconductor devices in the time domain. Pitfalls of the standard TLP and very-fast (VF) TLP setup will be explained, such as erroneous pulse reflections, misleading probe contact resistance, time artifacts and blind regions as well as the accuracy of transient trigger peak analysis for ESD protection devices.The human metal model (HMM) will be discussed versus application of the VF-TLP/TLP methods. Conclusions will round up the key statements.
