This paper presents the extraction of common mode (CM) and differential mode (DM) inductances of a common mode choke (CMC) using 3D finite element method (FEM). For optimal performance of the CMC, the effects of CM and DM currents on the magnetic core saturation are investigated. As the parasitic capacitance of a CMC is a critical parameter that affects its high frequency performance, the parasitic...
In high-speed electrical systems, power distribution network (PDN) with power ground planes (PGP) is widely used to gain effective high-speed decoupling. Rather than modelling such PDN from conventional steady-state analysis in the frequency domain, we propose its two-dimension (2-D) charge delivery model from charge delivery perspective in the time domain, which correlates better with the PDN real...
With increasing clock speed in high-speed digital design, proper impedance matching between the printed circuit board trace and the clock driver output is crucial for signal integrity design. Adding a series output resistor is a common technique to match a clock driver output to a high-speed signal trace for its simplicity and ease of implementation. The selection of the value of the series output...
