Abstract:
In this paper, the substrate parasitic has been added into the conventional MOSFET small-signal model for RFIC applications, and an extraction approach based on the curve-fitting method proposed by S. Lee also has been developed to accurately determine the whole model parameters. The agreement between the measured and simulated S-parameters up to 40GHz proves the feasibility of this modified extraction method.
