Frequency response characteristics of reference plane effective inductance and resistance [IC packaging]

A method which uses the partial element equivalent circuit (PEEC) method and electrical network theory to solve for the effective impedance matrix of reference planes is presented. The convergence and accuracy of the method are checked. The frequency responses of the effective inductance (L/sub eff/(f)) and resistance (R/sub eff/(f)) of reference plane are discussed. The effects of current redistribution and the skin effect on L/sub eff/(f) and R/sub eff/(f) are discussed. The effect of number of sinks and sources is examined.
