Dynamic C-V Characteristic for a Varactor Load Connected with a Transmission Line

Abstract

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 the incident waves for the nonlinear load, and estimated a dynamic C-V Characteristic that explain a relation between the incident and the reflected waves. This paper reports an simple experimental method to extract reflected waves at a varactor load and estimated results 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.
