An improved equivalent circuit model for graphene spiral inductors based on physical principles is pre-sented in this letter. The model is a π-circuit with additional parallel RC network in the series branch. A parameter extraction approach for proposed model, which combines the analytical approach and empirical optimization procedure, is also investigated. Good agreement is obtained between the simulated and measured S-parameters up to 40 GHz.
