Question 1
Design a BJT differential amplifier with specified input and output impedances. Calculate the necessary resistor values for a desired gain of 100.
💡 Hint: Make sure to consider how resistances affect gain and impedance.
Question 2
If given a common-mode gain of 10 and a differential gain of 100, calculate the common-mode rejection ratio (CMRR).
💡 Hint: Remember the formula for CMRR and apply it directly.
