dc.description.abstract | In this dissertation, MOSFET characteristics for terahertz (THz) detector application is analyzed to predict the THz responsivity, and is verified by SPICE simulation and 300 GHz on-wafer measurement. The analysis of THz responsivity and noise equivalent power (NEP) depending on the channel dimension and source/drain junction area of the MOSFET detector as well as on the frequency can provide a useful reference for the design of THz detectors. Also, a new architecture of THz imager adopting a VCO-based signal processing is proposed, and 0.5/1.5 THz array imagers are implemented in a 65 nm CMOS. The proposed THz imager architecture presents high signal-to-noise ratio performance, which results in about hundred times enhanced NEP and noise equivalent temperature difference (NETD) compare to previously reported THz imagers. Consequently, a high resolution THz image is obtained by monolithically implemented imager without requiring any external highly sensitive equipment. | - |
