THz_SPICE_model_2018

The file is for an improved compact SPICE model validated for the terahertz frequency range in a large dynamic range. The model validation
was done by comparing the simulation results with the analytical THz detection theory and with the measured data for the 130 nm InGaAs/AlGaAs HFETs. The modeling results are in good agreement with the analytical THz detection theory and with the measured sub-THz response dependence on the bias, power, and polarization. It
also demonstrates the response saturation previously measured at high intensities, and the resonant detection predicted by the detection theory for higher mobility
devices.
