This work focuses on the equivalent‐circuit modeling of microwave field‐effect transistors. Although the purely direct approach allows obtaining a good prediction accuracy in a straightforward way without the need of any optimization, optimization algorithms are often used to achieve an improved accuracy at the cost of a higher modeling complexity. The pros and cons of empowering the direct approach...
A novel nonlinear de-embedding procedure based on only the use of low- and high-frequency vector large-signal measurements is proposed. The nonlinear Q-V characteristics, along with the parasitic network, are here determined by combining vector measurements with numerical optimization. Consequently, the knowledge of their contributions allows one to retrieve the actual waveform at the current generator...
