Inductive characteristics of power distribution grids in high speed integrated circuits

The inductive characteristics of several types of gridded power distribution networks are described in this paper. The inductance extraction program FastHenry is used to evaluate the inductive properties of grid structured interconnect. In power distribution grids with alternating power and ground lines, the inductance is shown to vary linearly with grid length and inversely linearly with the number of lines in the grid. The inductance is also relatively constant with frequency in these grid structures. These properties provide accurate and efficient estimates of the inductance of power grid structures with various dimensions.
