Accurate frequency-dependent dielectric properties are important for accurate modeling of signal and power integrity problems. One method for extracting dielectric properties from fabricated multilayer printed circuit boards is based on the measured electrical property of fabricated transmission lines, denoted the “Root-omega” method. In this paper, the “Root-omega” method applied to the cases with...
Calculating the Green's functions in lossy layered media using the discrete complex image method (DCIM) is challenging, due to the difficulties in extracting the surface-wave poles that are very close to a branch cut. An efficient algorithm based on the contour method is proposed in this communication to locate these poles and calculate the residues. The proposed method is robust for both the lossless...
Signal integrity (SI) and power integrity (PI) modelling and design require accurate knowledge of dielectric properties of printed circuit board (PCB) laminate dielectrics. Dielectric properties of a laminate dielectric can be obtained from a set of the measured S-parameters on a PCB stripline with a specially designed through-reflect-line (TRL) calibration pattern. In this work, it is proposed to...
SerDes (Serializer/DeSerializer) is widely used in gigabit Ethernet systems, fiber-optic communication systems, and storage applications for high-speed data transmission between different ASICs (application-specific integrated circuit) with the significant advantage of saving package pin numbers. The channel connecting the Serializer/DeSerializer in two different ASICs on a PCB (Printed Circuit Board)...
Widespread use of the Web 2.0 Internet applications such as video streaming and social networking are continuously demanding higher bandwidth network equipment. Electrical designers increasingly face more and more challenges to deliver higher speed products within short development cycle due to design complexity and new multi-GHz signal integrity problems. This paper presents a modeling and simulation...
