6.4. ADC Performance Metrics and Specifications

Try these first

1. 1.

   Define resolution in the context of ADCs.

   Hint

   Think about how many distinct values a digital signal can represent.

2. 2.

   What is SNR?

   Hint

   Consider how noise affects the quality of a signal.

3. 3.

   What does SNR stand for?

   • Signal-Noise Ratio
   • Signal-to-Noise Ratio
   • Sound-to-Noise Ratio

   Hint

   It's a metric commonly used to assess signal clarity.

4. 4.

   True or False: A higher resolution leads to a higher number of discrete levels in ADC output.

   • True
   • False

   Hint

   Consider how bits relate to levels.

5. 5.

   You have a 12-bit ADC. What’s the total number of discrete levels it can output? If the reference voltage is 3V, what’s the resolution in volts?

   Hint

   Remember the formula for levels and resolution.

6. 6.

   Discuss the trade-offs devices face when selecting an ADC for portable applications requiring low power and high performance. What metrics are most critical to balance?

   Hint

   Reflect on application needs and how they drive design choices.
