Compute the characteristic velocity (delay per mm) of a repeated metal2 wire in the 180 nm process. A unit nMOS transistor has resistance of 2.5 kΩ and capacitance of 0.7 fF, and the pMOS has twice the resistance. Use the data from Figure Consider both minimum pitch and double-pitch (twice minimum width and spacing) wires. Assume solid metal above and below the wires and that the neighbors are not switching. .
