Abstract
An apparatus, system and method are described for impedance matching between a semiconductor package and a load on a board. In one embodiment of the present invention, a package trace is provided with an array of stubs that is designed to provide capacitance to the trace in order to more effectively match a wirebond. This improved match results in improvements in return loss, especially in higher speed applications such as broadband. Design parameters such as the width and length of each stub, and the spacing between the stubs may be varied depending on the impedance requirements of the trace.
