“…The impedance of the PGP can reach up to a large value when the frequency is the parallel resonance frequency. According to the Green's function in Equation ( 1), there is the relation k 2 10 ¼ k 2 ¼ ω 2 10 μ 0 μ g ε 0 ε g when the frequency is the parallel resonance of mode (1, 0), from which we can obtain that μ g ¼ k 2 10 ω 2 10 ε g ε 0 μ 0 of the PGP. However, to get such ε g and μ g , one should had the presimulated Z 11 in Figure 3.…”

“…Power ground plane (PGP) is one of the most widely used PDN which is constructed by two or multi layers of metal planes. For a rectangular PGP, lots of methods have been run out of such as the imagery method, 2 partial element equivalent circuit (PEEC) method 3,4 . Green's function which belongs to the mode method can also be used to calculate the impedance of PGP efficiently.…”

The power distribution network (PDN) is an essential component in high speed circuits, and the impedance calculation of PDN becomes a hot topic. In this paper, we proposed a method to calculate the impedance of power ground grid (PGG), which is one type of the PDN, by using artificial neural network (ANN). First, the PGG is equivalent to a simple power ground plane (PGP).The equivalent PGP has the same dimension and port location but different relative permittivity ε g and relative permeability μ g of the substrate compared to the original PGG. Then, ANN is used to calculate the equivalent ε g and μ g of the equivalent PGP. Thus, the impedance of equivalent PGP can be obtained by using Green's function. The proposed method has been validated by numerical and measurement examples. The agreement and difference of the impedance results in both examples are also analyzed.
