CLK
CLK
CLK
Given the circuit, each two-input XOR gate has a propagation delay of 80 ps and a
contamination delay of 40 ps. Each flip-flop has a setup time of 80 ps, a hold time of 50 ps, a
clock-to-Q propagation delay of 100 ps, and a clock-to-Q contamination delay of 70 ps.
(a) If there is no clock skew, what is the maximum operating frequency of the circuit?
(b) How much clock skew can the circuit tolerate before it might experience a hold time
violation?
