If this same wire continues for another 587.9μm to connect to a Mark s : second flip- flop, what will be the clock skew between the two flip- flops in 0/2 picoseconds? Neglect the input capacitance of the flip- flops. 4 Answer: Incorrect Correct answer: 150.5 Mark s for this s ubmis s ion: 0/2. 5 Mark s : 2/2 Timin...
