2.5. Sub-System Level Circuits

Try these first

1. 1.

   Define single-ended signaling.

   Hint

   Think about how the signal is referenced.

2. 2.

   What is a differential amplifier?

   Hint

   Consider what it does with two input signals.

3. 3.

   What type of signaling is referenced to a common ground?

   • Single-Ended
   • Differential
   • Both

   Hint

   Think about the simpler form of signaling.

4. 4.

   True or False: Differential amplifiers amplify both input signals equally.

   • True
   • False

   Hint

   Consider the defining function of a differential amplifier.

5. 5.

   Evaluate the performance of a differential amplifier when subjected to common mode and differential mode signals. Explain the implications for overall circuit performance.

   Hint

   Consider how each type of signal interacts with the amplifier.

6. 6.

   Design a current mirror for a differential amplifier, detailing component selection and the expected biasing characteristics.

   Hint

   Think about how current mirrors stabilize circuit performance.
