Abstract
An improved power distribution network for an integrated circuit package that reduces the number of power supply pins that are used in the pin array and achieves better operating performance. In a preferred embodiment, the ratio of power supply pins to input/output (I/O) pins is in the range of approximately 1 to 24 to approximately 1 to 52. In this embodiment, the integrated circuit package comprises a substrate, an integrated circuit mounted on the substrate, a first decoupling capacitor mounted on the substrate, and a second decoupling capacitor formed in the integrated circuit. The package is formed by coupling a power supply pin to both the first and second capacitors by a low frequency path and a DC path, respectively, and the first and second capacitors are coupled by a high frequency path.
