Analysis of noise coupling from a power distribution network to signal traces in high-speed multilayer printed circuit boards

Abstract

Abstract-As layout density increases in highly integrated multilayer printed circuit boards (PCBs), the noise that exists in the power distribution network (PDN) is increasingly coupled to the signal traces, and precise modeling to describe the coupling phenomenon becomes necessary. This paper presents a model to describe noise coupling between the power/ground planes and signal traces in multilayer systems. An analytical model for the coupling has been successfully derived, and the coupling mechanism was rigorously analyzed and clarified. Wave equations for a signal trace with power/ground noise were solved by imposing boundary conditions. Measurements in both the frequency and time domains have been conducted to confirm the validity of the proposed model.

Modeling and Analysis of Simultaneous Switching Noise Coupling for a CMOS Negative-Feedback Operational Amplifier in System-in-Package

“…Unfortunately, this results in a reference plane exchange from the power plane of Layer 3 to the ground plane of layer 2. This can cause a serious SSN coupling from the power/ground plane cavity to the signal via [15]- [18]. Model parameters of the microstrip line and a through-hole via for SSN coupling path 2 are listed in Table II.…”

“…The total the gate-source voltages of M 1 and M 2 by v sp,SSN and v in,SSN are obtained from the previously derived equations in Sections IV-C1 and C2., including (14), (15), (17), and (18). To describe these equations of the gate-source voltage in the time domain, we have the following equations:…”

“…The second SSN coupling path is the SSN coupling to the input of the OpAmp through a via transition in the package substrate. The via transition makes a signal trace exchange its reference planes from the ground plane to the power plane [16]- [18]. In this study, these two coupling paths were modeled based on the transmission-line matrix (TLM) method and a distributed circuit modeling approach [19]- [21].…”

Broadband Switching Noise Estimation of Resonant Low-Loss Structures for Unipolar Pulse Excitation

“…A highly relevant and practical example is the power distribution network (PDN) in printed circuit boards. In the recent years, a variety of approaches concerning switching-noise estimation in PDNs has been presented [2]- [5]. Examples with unipolar current pulses are frequently considered.…”

Analytical expressions for transfer function of supply voltage fluctuation to jitter at a single-ended buffer

“…The switching current flowing from power to ground through the logics and buffers results in significant fluctuation in the supply voltage. The supply voltage fluctuation can cause significant delay change in transmitter and receivers [2][3][4], and also can be electromagnetically coupled into signal lines in channels [5], as shown in Fig. 1 (b).…”
