Abstract:

In certain aspects, a device comprises a first processing unit; a first power distribution network coupled to the first processing unit; a first decoupling capacitor coupled to the first power distribution network; a second processing unit configured to be identical to the first processing unit; a second power distribution network coupled to the second processing unit; and a second decoupling capacitor coupled to the second power distribution network, wherein the second decoupling capacitor is configured to have different effect on the second power distribution network than the first decoupling capacitor on the first power distribution network.
