Patent ID: 7119631

Claim:
An off-chip LC (inductance-capacitance) circuit that communicatively couples to an integrated circuit, the circuit comprising: a first RF (Radio Frequency) choke that communicatively couples an off-chip supply potential node to a first pin of the integrated circuit; wherein the first pin connects to an on-chip supply potential node of a die that is implemented within the integrated circuit; wherein the on-chip supply potential node powers an on-chip PA (Power Amplifier) that is implemented within the die; a second RF choke that communicatively couples an off-chip ground potential node to a second pin of the integrated circuit; wherein the second pin connects to an on-chip ground potential node of the die; wherein the on-chip ground potential node serves as an on-chip ground reference of the on-chip PA; an off-chip joining capacitor whose ends communicatively couple to each of the first pin and the second pin of the integrated circuit; and an off-chip tuning capacitor whose ends communicatively couple to the first pin of the integrated circuit and an off-chip true ground potential node.
