Abstract :
We discuss the modelling, implementation and characterization of antenna-coupled field-effect transistor detectors for THz frequencies. Detectors have been fabricated using a commercial 65-nm CMOS foundry process. At 4.1 THz resonance frequency and optimum operation conditions a responsivity of 86 V/W and noise-equivalent power of 113 pW/√Hz has been measured.
