A system and method for providing on-chip voltage distribution and regulation. In accordance with the system of the present invention, an IC chip includes a source voltage plane having a source supply rail for supplying power to the IC chip and a source ground rail for sinking power supplied therefrom. At least one intermediate ground rail is connected between the source supply rail and the source ground rail to divide the source voltage plane into multiple intermediate voltage planes. The intermediate ground rail serves as a supply rail for a subsequent intermediate voltage plane such that the intermediate voltage planes are series-connected.
In an integrated circuit, a voltage distribution circuit for providing at least three voltage planes, the voltage distribution circuit comprising:
