Question 1

What is the common mode voltage?

  • Voltage affecting only one input
  • Voltage affecting both inputs equally
  • The voltage difference between inputs

💡 Hint: Remember the term 'common' relates to both inputs.

Question 2

True or False: An increase in common mode voltage inevitably increases distortion.

  • True
  • False

💡 Hint: Think about the relationship with saturation levels.

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.
