Abstract
A radio-frequency (RF) equivalent circuit model for the metal-insulator-metal (MIM) capacitor with both side bottom plate contact is presented. The proposed model consists of 3-distributed RC networks and substrate networks. The accuracy of the MIM capacitor model is verified for Z-parameters, effective capacitance (Ceff), quality factor (Q), and MIM capacitor impedance (Zc) up to 20GHz. The effects of substrate network components on MIM's frequency characteristics are also analysed through Z-parameters. Finally, the cutoff frequency of the MIM is extracted from Q-factor and Zc.
