Question 1

What does t_CQ represent in a D-Flip-Flop?

Time until the clock signal rises
Time taken for output to change after clock edge
Time taken for input signal to stabilize

💡 Hint: Think about what you measure after clock edges.

Question 2

True or False: A D-Latch responds to clock edges like a D-Flip-Flop.

True
False

💡 Hint: Reflect on the difference between level and edge sensitivity.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You have a flip-flop with a setup time of 150 ps, a hold time of 50 ps, and you need to transmit data at a clock rate of 2 GHz. If the data signal changes 120 ps before the clock edge, will you encounter issues?

💡 Hint: Check the timing relative to the clock edge.

Challenge 2 Hard

Given a system where metastability calculations indicate a flip-flop may sometimes resolve within 10 ns, what would you suggest to improve system reliability?

💡 Hint: Consider increasing the number of flip-flops or adding filtering stages.
