Experimental validation of system NEP of a single-pixel THz imaging camera in CMOS

Activity: Talk or presentationTalk or presentation at a conference

Description

CMOS technologies show great potential for realizing fully passive multi-pixel THz imagers without cooling the system. In order to achieve such high performance, system NEPs in the order of a few pW/sqrtHz are required, which are difficult to achieve in CMOS technologies. Accurate high-frequency models of the detectors, and an antenna-detector co-design are vital but not always readily available. This work presents the experimental derivation of a high-frequency model of the smallest Schottky Barrier Diode that is allowed for in a CMOS technology and the experimental validation of that model by means of a single-pixel THz imaging camera operating from 200 GHz to 600 GHz. The camera consists of a double bow-tie slot antenna in combination with a dielectric lens and offers an average system NEP of 50 pW/sqrtHz in the WR2 band.
