Superlattice castellated FETsResearchers from the University of Bristol and Northrop Grumman Mission Systems discovered a latch-effect in gallium nitride (GaN) that could lead to improved radio frequency device performance, crucial for enabling 6G devices. “We have piloted a device technology, working with collaborators, called superlattice castellated field effect transistors (SLCFETs), in which more than 1000 fins with sub-100 nm width help drive the current.

Synopsys’ Frank Malloy listens in on a panel discussing the engineering challenges introduced by multi-die designs, from multi-physics interactions that impact power and thermal integrity to the availability of multi-die packages and industry standards. Siemens’ Bruce Caryl shows how to determine how much a design’s power delivery network is contributing to jitter on the output drivers by using a 3D field solver and time-domain simulation.

Smart t-shirt with sound wavesResearchers at ETH Zurich developed a smart textile that uses acoustic waves passed through glass fibers to measure touch, pressure, and movement. The researchers said that using acoustic waves rather than electronics makes measurements more precise with low power consumption and the textiles lighter, more breathable, and easier to wash. It also uses readily available materials.

Siemens’ Stephen V. Chavez finds that proper PCB high voltage spacing between conductive elements is key to reliability and understanding the principles of clearance (through-air spacing) and creepage (along-surface spacing) is critical. Cadence’s Frank Ferro checks out how the new HBM4 standard boosts bandwidth and addresses key issues in the data center, including the growing size of LLM data sets, reliability, and memory efficiency.
