Unformatted text preview: 1.8V? c. Re-write your solution for part a in terms of area A given a uniform density of load points d (loads per unit area) with 7fF loads at each point. 8. Consider a clock grid consisting of a square lattice of minimal size wires, each with a resistance of 250 Ω /mm, a capacitance of 0.28pF/mm and a grid pitch (wire to wire spacing) of 25um. If driven from the center, what is the largest size that can be clocked before the rise time of the ter-minals increases beyond 200pS? b. If the grid wires above are sized to carry the same current density per segment, and drive a total unifrom load of capacitance 700pF in addition to the grid capacitance, how do you set the wire sizes of the grid as afunction of the radial distance from the center?...
