摘要：This letter presents a compact slot-array coupled terahertz (THz) detector achieving a high baseband responsivity of 10 MV/W. The core circuit of the THz detector is based on the principle of square-law detection and realized by a common-source structure. In order to reduce the impact of process variation, a novel bias scheme for pseudo resistor (PR) is proposed to stabilize the baseband bandwidth. A slot-array coupler is employed to extract the THz signal from waveguide for measurement requirement. Fabricated in a 65-nm CMOS process, the proposed detector demonstrates effective detection.
