Challenge Problems
Push your limits with challenges.
Question 1
A differential amplifier is designed with a given DC operating point. If the input common mode voltage is increased by a specific value, determine the new output swing limits.
💡 Hint: Use the relationships of voltage and currents for transistors in active regions.
Question 2
Evaluate how changing both resistors in a differential amplifier affects the input common mode range and output swing.
💡 Hint: Examine how changes in resistor values influence both voltage and current flow.
