| Abstract(in English) | Use of terahertz waves for imaging is gaining increased interest. A CMOS cascode amplifier biased near the threshold voltage of a MOSFET for terahertz direct detection is proposed. A CMOS terahertz imaging pixel is designed and fabricated on the basis of a low-cost 180 nm CMOS process technology. The imaging pixel consists of a microstrip patch antenna, an impedance-matching circuit, and the direct detector. The imaging circuit occupies 250 × 180 um^2. It achieves a responsivity of 51.9 kV/W at 0.915 THz and a noise equivalent power (NEP) of 358 pW/Hz^1/2 at a modulation frequency of 31 Hz. The NEP is estimated to be reduced to 42 pW/Hz^1/2 at a higher modulation frequency of 100 kHz. |
