Power Integrity Analysis of Power Distribution Network Segmented Using DGS–Electromagnetic Bandgap Structure in Mixed-Signal PCBs

“…In this demonstration, Port u is not used for the sake of simplicity. The positions of the other ports (x q1 , y q1 ), (x q2 , y q2 ), (x r1 , y r1 ), and (x r2 , y r2 ) are (5,4), (20,22), (20, 10.9), (24,12), and (24 mm, 0.9 mm), respectively. The power integrity characteristics of the PDN segmented by the DGS-EBG structure are analyzed using a self-impedance (Z 11 ).…”

“…In general, an inhomogeneous EBG-based PDN consists of several D-and NS-PDNs connected to each other through DGS-EBG arrays. Although various configurations of EBG segmentation for the inhomogeneous EBG-based PDN can be considered [19][20][21][22][23][34][35][36], we focus on the PDN configured as a non-closed-loop interface between an EBG array and a D-or NS-PDN. The non-closed-loop interface implies that the boundary between an EBG array and a D-PDN is different from the boundary for an EBG array and an NS-PDN.…”

“…As a solution to the noise problem, PDNs employing a segmentation technique have been extensively studied [6][7][8][9][10][11][12][13]. In particular, the PDN segmented by the electromagnetic bandgap (EBG) structure with a defected ground structure (DGS) is considered a promising technique for power/ground noise suppression [14][15][16][17][18][19][20][21][22][23]. Figure 1 illustrates the PDN employing DGS-EBG segmentation.…”
