Challenge Problems
Push your limits with challenges.
Question 1
You need to design a differential amplifier for temperature sensing that will amplify a small voltage difference caused by temperature variations. How would you choose the resistor values to achieve a needed gain of 10, and what considerations might you need based on sensor characteristics?
π‘ Hint: Balance gain with the input signal quality and sensor characteristics.
Question 2
Given a differential input of voltages 0.5V and 0V with Rf at 10kΞ© and R1, R2 both at 1kΞ©, calculate the output voltage of the differential amplifier.
π‘ Hint: Remember to apply the difference between inputs in your calculations.
