Abstract

Oscillation-based test (OBT) is one of the approaches for measuring static ADC parameters such as differential nonlinearity (DNL) and integral nonlinearity (INL) that can be implemented in a built-in self-test arrangement. As demonstrated in the paper, due to the arbitrary input signal phase shift and non-coherent input signal two oscillation periods are possible. This in turn manifests itself as a measurement uncertainty that should be considered in practice.
