Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a circuit using an Op-Amp to amplify a 100 mV signal to 1V using a non-inverting amplifier. Choose appropriate resistor values and explain your choice.

💡 Hint: Use the formula A_v = 1 + (R_1/R_2) to calculate required resistor ratios.

Challenge 2 Hard

Explain how varying R_f in an inverting amplifier influences the gain, and calculate the effect on output given R_f = 5kΩ and R_in = 1kΩ.

💡 Hint: Refer to the gain formula for inverting amplifiers.
