摘要: | A new T-model is developed to accurately simulate the broadband characteristics of on-Si-chip spiral inductors, up to 20GHz. The spiral coil and substrate RLC networks built in the model play a key role responsible for conductor loss and substrate loss in the wideband regime, which cannot be accurately described by the conventional pi-model. Good match with the measured S-parameters, L(omega), Re(Z(in)(omega)), and Q(omega) proves the proposed T-model. Besides the broadband feature, scalability is justified by the good match with a linear function of coil numbers for all model parameters employed in the RLC networks. The satisfactory scalability manifest themselves physical parameters rather than curve fitting. A parameter extraction flow is established through equivalent circuit analysis to enable automatic parameter extraction and optimization. This scalable inductor model will facilitate optimization design of on-chip inductor and the accuracy proven up to 20GHz can improve RF circuit simulation accuracy demanded by broadband design. |
