摘要
An integrated circuit including: an RF input/output; an on-chip digital interface including a plurality of IC pin connections wherein an output current from the on-chip digital interface is split into first and second parallel paths among the plurality of IC pin connections; first and second current sources; and a controller, wherein the controller is configured to determine a plurality of mutual inductances between the plurality of IC pin connections and the RF input/output; calculate a current ratio n based upon the plurality of mutual inductances between a first current driven on the first parallel path and a second current driven on the second parallel path; drive the first current source to produce the first current and the second current source to produce the second current wherein the first and second current have the determined ration; and measure a voltage at the RF input/output.
