  The kinetic inductance properties of a thin superconducting sample of
BSCCO-2223 compound is studied. A strong dependence of kinetic inductance with
the variation of applied magnetic field is found at low temperature in the
superconducting state. The kinetic inductance of a thin superconductor
increases linearly with increasing magnetic field. This behavior is used for
designing a superconducting modulator circuit. This behavior can be useful for
device applications and designing of superconducting electronic circuits like
superconducting power amplifier, superconducting transmitter and
superconducting ac current controller.
