Claim Text:
1. A circuit comprising: a core circuit operative to sink a first current from a first internal power supply node; a power bouncing reduction circuit operative to receive power from a second internal power supply node and sourcing a second current to the first internal power supply node in accordance with a change of voltage at the first internal power supply node, wherein the power bouncing reduction circuit comprises: a high-pass filter operative to receive the voltage at the first internal power supply node and outputting a high-pass filtered voltage; an amplifier operative to receive the high-pass filtered voltage and outputting a control voltage; and an output stage for sourcing the second current from the second internal power supply node to the first internal power supply node in accordance with a control by the control voltage; and a package operative to couple the first internal power supply node and the second internal power supply node to a first external power supply node and a second external power supply node, respectively.
