An integrated circuit package having a multi-segment transmission line transformer for impedance matching a packaged integrated circuit, such as a driver or receiver, to a printed circuit board (PCB) transmission line to which the packaged chip is attached by, for example, solder balls. In one exemplary embodiment, a three-segment transmission line transformer provides improved broadband performance with the advantage of having a middle segment with a flexible length for easier routing. The length of each end segment of the three-segment transformer is adjusted to provide at least partial cancellation of reflections between the PCB and the transformer, and between the transformer and a circuit on the integrated circuit, respectively. Further, the inductive reactance of the solder balls and via wiring may be cancelled out by the transformed chip impedance to provide a non-inductive termination to the PCB transmission line at approximately one-half the highest data rate of the channel.
