    How can they SPICE model two distinct serially connected resistors (Rls,
    Rcs - respectively Rll, Rcl) inside a power MOSFET? Are they kidding us
    ;-) If so is that useful in the model?:

    Is it possible (how?) to measure the internal parasitic components with
    a homemade impedance bridge?:

    Can this be used to measure the guts of a power MOSFET?:

    HP4194A is not within my range. Can HP4194A automatically deduce the
    power MOSFET guts?

    How can they do that? For a novice like me it look like magic:

    HFSS (high-frequency structural simulator), is a general-purpose field
    solver that also allows Spice modeling for S parameters and matrix solvers.

    Can somebody give some hints?
