Abstract
In one embodiment, an integrated circuit (IC) includes a power distribution network having a first set of power distribution lines connected to a source voltage and a second set of power distribution lines connected to a ground voltage, and a first capacitor. A first variable resistive element is electrically coupled in series with the first capacitor between the first and second sets of power lines of the power distribution network. A control circuit is coupled to the variable resistive element and is configured and arranged to adjust a level of resistance of the first variable resistive element in response to an input signal. The adjustment of the level of resistance adjusts an equivalent series resistance of the power distribution network.
