(35 pt) Q3 Clock distribution network is shown in the following Figure. Vin is the input signal that changes from 1.2 V to 0 at t-0. Assume an ideal inverter. Each segment of the clock distribution network is formed using Polysilicon layer with segment length (wire length) of 500 im and segment width (wire width) of 5 μm. Poly wire area capacitance is 88 aF/um and a poly wire fringing capacitance is 54 aF/um. Assume POLY sheet resistance of 12 Ω/per square. (a) Using equivalent a-model for the distributed RC line, draw the tree-structured RC network for the clock distribution network. (b) Estimate the current supplied by the inverter att 0+. Assume there is no internal charge stored in the network when t s0+ (c) Determine the time constants at nodel and nodeR1. (d) How long does it take nodel and nodeR1 to reach to 50% of their final values?
