Question 1

What is the main difference between a latch and a flip-flop?

Latches are edge-triggered
flip-flops are level-triggered.
Latches are level-triggered
flip-flops are edge-triggered.
Both function the same.

💡 Hint: Think about how each component responds to the clock signal.

Question 2

True or False: Setup time is the duration that data must be stable before the clock edge.

True
False

💡 Hint: Consider the timing relationship in flip-flops.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a D-Flip-Flop circuit and calculate the expected t_CQ if you know the transistor characteristics and clock edge. Discuss how you would adjust transistor sizes to minimize t_CQ.

💡 Hint: Consider how width and length ratios impact performance.

Challenge 2 Hard

In a system where multiple flip-flops are connected, explain how to mitigate metastability issues across different clock domains.

💡 Hint: Think about how clock signals can affect data transfer.
