A passive 480-GHz frequency doubler based on accumulation-mode MOS varactor in CMOS process is reported. Using a compact partially-coupled ring structure, the doubler achieves a simultaneous broadband matching for fundamental and 2nd-harmonic signals. With optimized gate length and oxide thickness, the MOS varactor achieves a dynamic cutoff frequency of 870GHz while sustaining large voltage swing...
Millimeter and sub-millimeter-wave imaging using solid-state circuits is gaining attention for security and medical applications. To lower cost and increase integration, MOSFETs in CMOS are being investigated for implementing broadband detectors [1–3]. However, neither measured noise-equivalent power (NEP) nor noise floor of the imager was given in [1]. Although NEP of 17pW/Hz1/2 was achieved at 650GHz...
