In this study, the kinetic inductance of a YBCO coplanar transmission line was measured to realize a parametric amplifier. A bias current was applied to the transmission line, and the characteristics were compared for different lengths of line. The kinetic inductance showed a clear square characteristic with respect to the current. From the results obtained, we discuss the magnitude of the nonlinearity and other issues.
