Zhi Hu received his B.S. degree from Fudan University in 2015 and his M.S. degree from MIT in 2017. In the summer of 2016, he was a visiting researcher at IHP Microelectronics, Germany. He won the Best Student Paper Award, 2nd place of the 2017 IEEE Radio-Frequency Integrated Circuits Symposium.
Terahertz (THz) spectrum is important for sensing and high-speed communications. Cost and system integration considerations make on-chip THz systems desired. This talk presents two high-performance THz chips based on 2D coherently-coupled active antenna arrays: a high-power 1-THz radiator array on SiGe and a sensitive 240-GHz heterodyne receiver array on CMOS, for high-spatial-resolution high-SNR sensing applications.
