5.3.1. Gain Mismatch

Try these first

1. 1.

   What is gain mismatch?

   Hint

   Think about how different values can affect the output.

2. 2.

   How does threshold voltage impact gain?

   Hint

   What kind of voltage is needed for a transistor to turn on?

3. 3.

   What is a key consequence of gain mismatch in analog circuits?

   • Improved output accuracy
   • Distortion in the output signal
   • Lower power consumption

   Hint

   Consider what happens when components don't work as expected.

4. 4.

   True or False: Gain mismatch only occurs in differential amplifiers.

   • True
   • False

   Hint

   Think about different circuit types where this could happen.

5. 5.

   Design an analog circuit with an emphasis on minimizing gain mismatch. List the components and techniques you'd use.

   Hint

   What components can you use that will naturally have matched characteristics?

6. 6.

   Analyze the impact of a 10% gain mismatch on a differential amplifier's performance. Estimate the distortion introduced and how it might affect output signals.

   Hint

   Consider what a mismatch means for audio clarity or fidelity.
