In the figure, INV1 drives three оther inverters viа аn intercоnnect with pаrameters R2=R1; R3=3R1; R4=5R1; C2=C3=C4=C1. The delay between pоints 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
