In the figure, INV1 drives three other inverters via an interconnect with parameters R2=R1; R3=3R1; R4=5R1; C2=C3=C4=C1. The delay between points A and B is 150 ps. Determine the delay between points A and B if C4 is tripled and R4 and R1 is halved. Use Elmore’s delay formula and ignore all inverter delays (assume they are very fast).  ELMORE-UPSCALED.jpg

H-tree configuration is useful and allows late design changes, since clock is easily accessible at various points on the die.

MULTIPLE ANSWER PROBLEM:  Determine inverter tapering size A, and Dynamic power dissipation P of 3rd inverter. Figure shows the inverter string design in a 0.6 micron 3.3 V CMOS technology. To optimize for the delay, each inverter is made A times larger than the previous inverter stage. Assume that the input and output capacitance of the first inverter (before the second stage connected) is given as 12 fF and 5 fF, respectively. Also, take the load capacitance Cload as 36,000 fF. The number of stages N calculated to be 8. Determine the tapering size A Determine the dynamic power dissipation of the 3rd inverter at a switching frequency of 1 GHz.  For this you need to calculate the total load capacitance at the output of 3rd inverter and then use dynamic power formula P= CLVDD2f Choose the values closest to what you have found. Assume minimum size inverter has Rn=12k/sq, Rp=36k/sq (in case you need it).   buffer-UPSCALED.jpg
