Challenge Problems
Push your limits with challenges.
Question 1
Given a differential amplifier with a supply voltage of 15V and a common mode voltage of 6V, determine the maximum output swing for both positive and negative outputs while avoiding saturation. Assume resistances and currents provided boost amplifier accuracy.
💡 Hint: Use related formulas to calculate voltages and resistances influencing output.
Question 2
Analyze how different thresholds for common mode voltage could affect the operation ranges of an amplifier with fixed resistive loads at various settings of input signals. Provide examples.
💡 Hint: Consider how changes impact gain and operational integrity.
