A circuit consists of three gates: A with a delay of 5 ns, B with 10 ns, and C with 15 ns. If they are in series, determine the critical path delay and the maximum clock frequency if t_setup is 2 ns and t_CQ is 3 ns.
💡 Hint: Add up the delays for the critical path and apply the frequency formula.
Discuss how parasitic capacitances can affect propagation delay in a circuit and propose a method to reduce delay.
💡 Hint: Consider the physical properties of circuit elements.
