Abstract :
We present a broadband distributed parasitic equivalent circuit model to accurately reproduce the frequency response of electromagnetic (EM) field couplings within the structure of submillimeter-wave (sub-mmW) high electron mobility transistors (HEMTs) in terahertz (THz) band. We also develop a novel systematic multi-step parameter extraction algorithm. The accuracy of the suggested extraction procedure is validated through extensive comparisons between full-wave (FW) simulated, measured, and modeled frequency responses of the presented test standards up to 750 GHz.
