Crosstalk is induced by a reflected wave of a load connected with a transmission line. Thus, analysis of the reflected wave is important. The reflected wave generated from a nonlinear load is complicated. In order to estimate the complicated reflected wave, we measured the reflected and incident waves for the nonlinear load and estimated the dynamic C-V characteristic, which explains the relation between the incident and reflected waves. This paper reports a simple experimental method of extracting reflected waves at a varactor load and presents estimates of the dynamic C-V characteristic of the load. It is shown that the reflected voltage waves simulated using the dynamic C-V characteristic agree with the measured results. © 2009 Wiley Periodicals, Inc.
