Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What is the output of a comparator if the non-inverting input is greater than the inverting input?

💡 Hint: Think about which input is larger.

Question 2

Easy

What state does the output of a comparator assume when both inputs are equal?

💡 Hint: Consider the situation when the voltages are the same.

Challenge Problems

Push your limits with challenges.

Question 1

You have a comparator with fixed reference voltage set at 2.5V. If the input voltage fluctuates between 1V to 3V, describe the output behavior when the input crosses the reference voltage.

💡 Hint: Consider the point at which the input voltage transitions.

Question 2

Design a comparator circuit that triggers an alert when the input voltage drops below a certain level. Explain the components needed and how they work together.

💡 Hint: Think about how to connect the circuit to make it responsive.
