Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a composite circuit using both inverting and non-inverting configurations to achieve a gain of 10. Specify resistor values.

💡 Hint: You can mix configurations to gain a desired overall effect.

Challenge 2 Hard

If a non-inverting amplifier has Rf = 50kΩ and Rin = 10kΩ, what is the overall gain? Also, calculate the output for an input of 2V.

💡 Hint: Use the gain calculation first, then apply it to the output voltage.
