Future Systems-on-Chip for Full Spectrum Utilization from RF-to-Optics
Future radio, radar, and interconnect systems demand ever increasing bandwidth, resolution, range, and performance, along with cost effective integrated solutions enabled by junction level hetero-integration (i.e. the Best Junction for the Function). While deeply scaled CMOS excels in mixed signal system on chip (SoC) implementations, it falls short in delivering the high drivability, linearity, and efficiency required for effective signal transmission. Hetero integrating III N materials onto CMOS drain terminals offers a promising pathway to extend system operating range and meet the needs of Beyond 5G/6G sensing and communications. This approach enables seamless RF to optical spectrum scaling while addressing critical challenges in bandwidth, range, resolution, manufacturability, and cost.
BIO: Dr. M.C. Frank Chang is the Wintek Chair in Electrical Engineering and Distinguished Professor at UCLA. Throughout his career, he has focused on the research and development of high-speed semiconductor devices (i.e. HBT/BiFET) and high-performance Systems-on-chip for radio, radar, imager, spectrometer, RF-interconnect and edge-AI accelerators.
