9.2.2. Design Considerations for Mixed-Signal CMOS Circuits

Try these first

1. 1.

   What is the main purpose of an ADC?

   Hint

   Think of how we digitize sound.

2. 2.

   Name one technique used to minimize noise in mixed-signal circuits.

   Hint

   Consider physical barriers.

3. 3.

   What is the role of an ADC in mixed-signal circuits?

   • Converting digital signals to analog
   • Converting analog signals to digital
   • Filtering signals

   Hint

   Think conversion.

4. 4.

   True or False: Proper clock distribution is essential only for digital circuits.

   • True
   • False

   Hint

   Consider what keeps everything in sync.

5. 5.

   How would you design a mixed-signal circuit that incorporates both ADCs and DACs for a high fidelity audio application? Discuss the challenges you might face.

   Hint

   Think about what makes audio clear and crisp.

6. 6.

   In a mixed-signal system with separate analog and digital grounds, explain how you would handle power supply noise.

   Hint

   Reflect on isolating digital buzz from clean audio output.
