“…The SSN leads to the cavity resonance modes within the parallel-plate waveguide-type power/ground planes. The resonance modes among the power and ground planes cause serious signal integrity (SI) or power integrity (PI) problems for the high-speed circuits [1][2][3].…”

Abstract-A novel vertical cascaded planar electromagnetic bandgap (EBG) structure is proposed for SSN suppression with the ultrawideband at the restraining depth of −30 dB by analyzing the simultaneous switching noise (SSN) suppression mechanism and the equivalent circuit model for EBG structure. Moreover, the SSN suppression bandwidth can be broadened by using different novel EBG structures required by vertically cascading different planar EBG structures. In addition, the structure is verified to meet signal integrity (SI) by the time-domain simulation. The tested results show that the presented EBG is accordant to the simulated results of the theory method by the vector network analyzer. The proposed structures provide a new designing method for EBG structures to improve the ability of suppressing SSN.

“…If we can reduce resonant impedance amplitude, then we will effectively lower behavior modes (TE and TM modes) along PCB edges [1][2][3][4][5][6][7][8][9][10][11]. We employ the use of absorption material to mitigate cavity resonant effect and PDN impedance noise from powerground planes.…”

Abstract-In this paper, we present an approach to reduce the cavity resonant edge effects in printed circuit boards (PCBs) and semiconductor packages. Power supply noise, in the form of fast changing currents (di/dt), traverses the power-return paths of PCBs and semiconductor packages using power vias. The cavity effects produce considerable level of noise along the edges of PCB and integrated circuit (IC) package power planes due to signal coupling between vias and reflection from PCB edges with transient currents. The cavity effects also amplify the electromagnetic radiation from PCB edges, which are major sources of EMI/EMC problems in electronic devices. By using absorbing material and decoupling capacitors (de-caps) on power distribution networks (PDNs), we observe considerable mitigation in impedance noise, signal noise and electromagnetic interference/compatibility (EMI/EMC) issues caused by the cavity effects. In particular, simulation results show notable reduction of upper peak (anti-resonant) impedance noise and reduction in radiated emissions by as much as 20 dB. This article presents a comparative case-study using various models (Section 3) and report on their effectiveness to reduce the cavity effects. The models are listed as (1) "Original" model, (2) "Absorbing material along the edge" model, (3) "MURATA based De-cap only" model and (4) "Absorbing material along the edge w/De-cap" model. The used capacitance ranges between 0.1 µF and 22 µF. The ESR and ESL range between 2 mOhm-20 mOhm and 238 pH-368 pH, respectively. Conclusively, we learn by adding absorbing material along the PCB edges with a few decoupling capacitors. The PDN impedance noise is improved, and EMI issues in PCBs and semiconductor packages suppress the cavity effects.

“…However, the suppression of SSN is worse than other methods. Literature [5] proposes a new method to estimate SSN directly from the power delivery network (PDN) frequency-domain impedance in order to reduce the time-domain simulation of SSN and computational burden, which is based on the periodic characteristics of the switching current and the SSN produced by one current pulse. However, the method is fit for analysis of PDN.…”

“…The degradation of the signal integrity (SI) due to the simultaneous switching noise (SSN) has become a choke point to the designing and manufacturing of the high-speed digital circuit with increasing requirements of high clock frequency [1][2][3][4][5][6]. In [1], EBG (electromagnetic bandgap) surfaces suppression of the PPW noise by 53% is achieved based on time-domain reflectometry experiments, while maintaining the signal transmission quality within the required specifications for common signaling standards, using three layers structure so that increases the cost of the fabrication.…”

Abstract-The traditional coplanar electromagnetic bandgap (EBG) structure is analyzed. The method is studied to lower the center frequency and broaden the bandwidth in this paper. A novel structure of U-bridged EBG power plane is proposed. The simulation and test results show that the bandwidth of the new structure is 4.32 GHz, and the lower side cutoff frequency is at 380 MHz with the stopband depth at −40 dB. The elimination of simultaneous switching noise (SSN) as this kind of U-bridged coplanar EBG structure is more effective below 1 GHz. In addition, the eye diagram of the structure is analyzed. The degradation of the maximum eye open and the maximum eye width on the structure is about 1.2% and 5.7%, respectively. Finally, the IR-drop and dc resistance is accurately investigated through 3-D simulations.
