MIM serie capacitor model for MMIC design application

A new proposed Metal-Insulator-Metal (MIM) serie capacitor model for Monolithic Microwave Integrated Circuit is presented. The MIM serie capacitor model covers the frequency range up to 40 GHz for millimeter-wave circuit design application. The parasitic elements of model are extracted by parameters fitting optimization between the measured S-parameters and model simulated result. The relationship between the optimized parasitic element values and the dimension data of capacitor structure can be expressed.
