Analog-to-digital Converter - Testing

Testing

Testing an Analog to Digital Converter requires an analog input source, hardware to send control signals and capture digital data output. Some ADCs also require an accurate source of reference signal.

The key parameters to test a SAR ADC are following:

  1. DC Offset Error
  2. DC Gain Error
  3. Signal to Noise Ratio (SNR)
  4. Total Harmonic Distortion (THD)
  5. Integral Non Linearity (INL)
  6. Differential Non Linearity (DNL)
  7. Spurious Free Dynamic Range
  8. Power Dissipation

Famous quotes containing the word testing:

    “Now I see that going out into the testing ground of men it is the tongue and not the deed that wins the day.”
    —Sophocles (497–406/5 B.C.)

    “Today so much rebellion is aimless and demoralizing precisely because children have no values to challenge. Teenage rebellion is a testing process in which young people try out various values in order to make them their own. But during those years of trial, error, embarrassment, a child needs family standards to fall back on, reliable habits of thought and feeling that provide security and protection.”
    —Neil Kurshan (20th century)

    “Traditional scientific method has always been at the very best 20-20 hindsight. It’s good for seeing where you’ve been. It’s good for testing the truth of what you think you know, but it can’t tell you where you ought to go.”
    —Robert M. Pirsig (b. 1928)
