On the co-design between on-chip antennas and THz MOSFET direct detectors in CMOS technology

This paper reports on co-design between CMOS direct detectors and silicon lens-integrated on-chip antennas. Due the appropriate impedance characteristics of the differentially driven antenna, broadband detector operation over multiple hundred GHz centered around 900 GHz could be achieved. The overall pixel layout is fully compatible with an industry qualified CMOS technology.
