Abstract :
This paper describes the of a 90 nm CMOS sub-THz detector array ASIC. The sub-THz detector array is an integrated system composed of silicon field effect plasma wave sensors, various integrated antennas, pre-amplifiers, ADCs, and digital domain lock-in amplifier detector. The peak responsivity is found 185 kV/W@365 GHz and 52 kV/W@470 GHz and at the detectivity maximum NEP ~ 20 pW/Hz-1.
