US Patent 8021973 System and method to reduce the bondwire/trace inductance

A method and system for reducing the inductance on an integrated circuit. The method and system comprises providing a first differential line, including a first input and a first output, the first differential line including at least two bondwire traces which are coupled in parallel. The method and system also comprises providing a second differential line including a second input and a second output, the second differential line including at least two bondwire traces which are coupled in parallel, the first differential line being of opposite polarity to the second differential line. The method and system further comprises cross-coupling of the first input with the second input and the first output with the second output to reduce the inductance caused by bondwire traces. A technique in accordance with the invention uses the coupling factor K to help to further reduce the inductance. By changing the input ordering of differential bondwires/traces, the bondwire/trace magnetic coupling factor K can be used to reduce the line inductance.
