Abstract
Techniques to deliver a precision low noise reference voltage to a precision analog-to-digital converter without the need of a reference buffer or digital correction. In an example, a technique can use an integrated resistor divider and external capacitor to derive a low noise precision reference voltage either from the power supply of the ADC, or from an integrated reference source.
