Current has to flow through an interconnect 1 cm in length, 2 mm wide and 1 mm deep. Aluminum, which is currently used in integrated circuits has a resistivity p of 2.65 x 10-0m. Copper has a resistivity p of 1.68 x 10-m. The resistance of a wire is given by R = 2 where L is the interconnect length and A is the cross-sectional area of the interconnect. Assume that we applied 500MHz signal to the interconnect. Draw an approximate waveform of the signal observed on the interconnect. Note: The charge/discharge time for an RC circuit is approximately 5r. Assume that we applied 1GHz signal. Draw an approximate waveform of the signal observed on the interconnect. Note: The charge/discharge time for an RC circuit is approximately 5t.
