摘要：
This paper reports on cold operation of a SiGe HBT in an experimental 0.13-mu m technology as a broadband THz power detector and compares it against the classical forward-active operation range based on a frequency-dependent nonlinear device model. In the near-THz fractional bandwidth of 250-1000 GHz, a state-of-the-art optical NEP of 3.9-28 pW/root Hz and 2.116 pW/root Hz for cold and forward-active operation, respectively, was measured for the antenna-coupled THz detector comprising 2 devices in common-base (CB) configuration.
