Patent ID: 7990158

Claim:
A method for determining characteristic line parameters of a device by measuring scattering parameters (S-parameters) as a function of frequency of transmission lines, the device comprising a voltage mesh, a ground mesh, a transmission line and one or more neighboring signal lines, the ground mesh disposed in metal layers parallel to metal layers of the voltage mesh, the transmission line and the one or more neighboring signal lines disposed between said voltage mesh and said ground mesh, wherein said one or more neighboring signal lines are parallel to said transmission line, the method comprising: connecting a first voltage mesh end and a second voltage mesh end of said voltage mesh to a reference ground, a mesh comprising an electrically connected plurality of device wires in a device layer orthogonal and electrically connected to another plurality of device wires in a device layer; symmetrically to said connection of said first voltage mesh end and said second voltage mesh end, connecting a first ground mesh end and a second ground mesh end of said ground mesh to said reference ground; terminating only one end of the transmission line with a low impedance termination; terminating each of said neighboring signal lines with a low impedance termination at a first end; and terminating each of said neighboring signal lines with high impedance at a second end; and measuring scattering parameters as a function of frequency of said transmission line disposed between said grounded meshes.
