You are designing a differential amplifier with an ideal differential mode gain of 100 and a common mode gain of 0.01. If the input signals are 0.2V and 0.1V, what is the expected output?
💡 Hint: Focus on the gain calculations.
How will the performance of your mixed signal (both common mode and differential) be impacted if your differential amplifier is not properly biased?
💡 Hint: Consider the impact of bias in circuit operations.
