Equivalent transition capacitance of a nonlinear devise connected with a transmission line for crosstalk analysis

In crosstalk analysis, reflection of a load connected with terminating a transmission line is important. In order to investigate behavior of the reflection, we measured the reflected and the input voltages for the load, and estimated equivalent transition capacitances that explain a relation between the input and the reflected voltages. This paper reports an experimental method to extract reflected voltages at a varactor load and estimated results of the equivalent transition capacitance of the load. It is shown that the reflected voltages simulated using the equivalent capacitance agree with the measured results.
