A circuits become faster, more concern needs to be focused onpackaging and interconnects in order to fully utilize deviceperformance. One area of concern is with the package leadsbetween the chip and the board environment. The current flowinginto or out of an integrated circuit is conducted through a lead frametrace and bonding wire connecting the integrated circuit to outsidecircuitry. these leads are circuit elements, inductors, and have adefinite effect on the circuit performance because they generatenoise in high-speed applications.Inductance is the measure of change in the magnetic fieldsurrounding a conductor resulting form the variation of the currentflowing through the conductor. The change in current through theinductor induces a counter electromotive force, EMF, which opposesthat change in current.
