Challenge Problems
Push your limits with advanced challenges
Given A_d = 50 and A_c = 0.2, find v_o for v_in_d = 3V and v_in_c = 1V. Discuss how the values of A_d and A_c affect the output.
💡 Hint: Apply the given gains to their respective inputs.
How does increasing A_c affect overall circuit performance when A_d remains constant? Provide an analysis of implications and potential solutions.
💡 Hint: Think of how the signal integrity can be compromised.
