Abstract:
1. An electronic device comprising: a packaged semiconductor chip having a plurality of chip leads extending therefrom, a first group of the decoupling capacitors electrically connected to a first select group of the chip leads in a first select region of the chip leads, the first group of decoupling capacitors each having a first decoupling capacitance and each having a first self-resonance frequency; a second group of the decoupling capacitors electrically connected to a second select group of the chip leads in the first select region of the chip leads, the second group of decoupling capacitors each having a second decoupling capacitance and each having a second self-resonance frequency, wherein the second decoupling capacitance differs from the first decoupling capacitance, and wherein the second self-resonance frequency differs from the first self-resonance frequency; and a first bulk capacitor electrically connected to at least one of the first select group of the chip leads in the first select region, the first bulk capacitor having a first bulk capacitance, wherein the first bulk capacitance differs from the first and second decoupling capacitances.
