Unformatted text preview: out A 15 fF 5 fF 3. Elmore Delay Find the RC propagation delay from the output of gate 1 to the input of gate 2. Assume that all gates have an input capacitance of 10 fF and an output capacitance of 5 fF. Assume that the wire is a one-sided minimum-width metal-4 wire over field oxide and that the equivalent resistance of gate 1 is 1k . Use a model for each wire-segment and the Elmore approximation to find the delay. Use the parasitic capacitances and resistances given in the hand-analysis parameters posted on the course web-page.
