Parameter extraction is performed from real and imaginary parts of the Y-parameters. Each parameter is extracted from the Y-parameter equations which contain frequency terms. Simulation Standard.Apr 20, 2021 · V S in a small signal model is placed between gate and source terminal. When input signal V S is very low, the MOS transistor can be replaced by the small-signal model. The flow of current is clockwise and is gmV GS, and V 0 is connected to load resistance RL. R 0 and RL are in a parallel arrangement. Therefore, gain here will be gmV GS.
