Challenge Problems
Push your limits with challenges.
Question 1
You have a differential amplifier with Rβ = 20 kΞ© and Rβ = 80 kΞ©. If you input voltages of 4.0V and 1.0V, what is the output voltage?
π‘ Hint: Find the difference between the input signals first.
Question 2
In a laboratory setting, you are tasked with designing a differential amplifier with a gain of 15 using specified resistors. If Rβ = 5 kΞ©, what should Rβ be? What about Rβ and Rβ if you want the circuit balanced?
π‘ Hint: Remember to use the gain formula for differential amplifiers.
