How the Voltage Reference Affects ADC Performance, Part 1
May 26, 2010 | Bonnie Baker and Miro Oljaca
When designing a mixed-signal system which has an analog-to- digital converter (ADC), it is critical to understand how this device interacts with the voltage reference and voltage reference buffer. This article, the first of a three-part series, looks at the fundamental operation of an ADC independently, exactly as many designers do, and then at the performance characteristics that have an impact on the accuracy and repeatability of the system.
