Abstract
This paper presents a THz imaging system composed of a signal source and a signal sensor in CMOS technology. The signal source integrates a 338 GHz oscillator in 40-nm CMOS and an antenna array on a Benzocyclobutene (BCB) carrier using the SoP (System-on-Package) technique. The measured EIRP achieves +8 dBm. The signal sensor is implemented in 0.18 μm CMOS. The measured maximum responsivity is 632 kV/W at 332 GHz. The signal source and signal sensor consume dc power of 37.5 mW and 7.92 mW, respectively. The resolution of the proposed THz imaging system is 4 mm.
