Talk abstract: CMOS technology continue to provide both opportunity and challenge for circuit designers at mm-wave frequencies. At frequencies beyond transistor cutoff CMOS can still provide compact passive detection for imaging, but sensitivity, on-chip antennas and array properties still pose a challenge. We propose hybrid array integration on board and demonstrate a 6x6 imaging array at 0.3THz with on-chip low noise readout. Leveraging on our legacy work on detectors and harvesters around 100GHz, mainly based on reverse Colpitts topology, we focus now on rectifiers for low power harvesting at 5G mm-wave frequencies around 28GHz with a new look at what makes high frequency rectification efficient. We propose and demonstrate multiple techniques of enhancing output voltage and power efficiency at input power levels down to -20dBm, as well as integration with antenna-in-package and arrays.
Speaker Bio: Prof. Eran Socher has been with the School of Electrical and Computer Engineering of Tel Aviv University since 2008 and heads the School since 2023. His research focuses on mm-wave CMOS circuits for high speed communication, sensing and imaging. He has been a Visiting Professor at UCLA (2006-2008) and University of Toronto (2015-2017) and received his BA in Physics, BSc, MSc and PhD in EE, all from the Technion.
