Abstract :
Scattering parameters of wide MOSFET devices have been measured at the wafer level in the frequency range up to 1 GHz. These scattering parameters are converted to Y-parameters for device characterization and compared with SPICE simulations of L-, Π-, and T-ladder distributed RC circuits taking into account the effect of distributed gates. Good experimental agreement shows that this effect can be modeled appropriately by multisection RC ladders, especially T-ladder circuits. Differences among ladder circuits in modeling this effect are discussed qualitatively
