Abstract :
Based on the FDTD modeling approach, the coaxial feeding effects on the measurement of the transfer impedance for the power distributions in the high speed digital PCB are investigated. The influences of different probing loading conditions on the transfer impedance behavior are studied. In addition, the transfer characteristics of the power distributions in the realistic digital circuits are simulated in the FDTD model. The simulated difference of the transfer behavior between the realistic case without coaxial feed and the measured results with probing effects is also compared
