Abstract
An electronic THz transmissive imaging system is presented in this work. This system is composed of a CMOS signal source, a CMOS signal sensor, lenses, and commercial electronic chopping components. The output frequency of the signal source is 339 GHz, and the responsivity of the signal sensor is 200 kV/W. The total dc power consumption of those CMOS circuits is 91.02 mW. Using electronic chopping at the frequency up to 100 kHz helps improve the system dynamic range and makes imaging feasible. The resolution of the realized imaging system achieves 2 mm.
