2.7.2. Emphasis on Design Approaches

Try these first

1. 1.

   What is single-ended signaling?

   Hint

   Think about what reference point means in circuits.

2. 2.

   What is the primary role of a differential amplifier?

   Hint

   Consider what it means to compare two signals.

3. 3.

   What is a differential amplifier primarily designed to do?

   • Amplify a single input
   • Amplify the difference between two inputs
   • Provide power to load

   Hint

   Consider what 'difference' means in terms of voltages.

4. 4.

   True or False: Single-ended signaling is less susceptible to noise than differential signaling.

   • True
   • False

   Hint

   Think about how each method handles interference.

5. 5.

   Given two input signals A and B with values 5V and 3V respectively, calculate the output voltage of a differential amplifier with a gain of 10.

   Hint

   Use the formula for output voltage with respect to gain and input difference.

6. 6.

   Consider a circuit where feedback reduces gain by 50%; if the original gain was 40, what is the new gain? Discuss how this impacts the amplifier's frequency response.

   Hint

   Pay attention to how feedback affects overall gain.
