Oscillation-based test (OBT) of analog-to-digital converters (ADCs) represents a viable option for low-cost built-in self-test in mixed-signal design. While numerous papers have addressed implementation issues, little attention has been paid to the measurement accuracy. In this paper we highlight an inherent measurement uncertainty which has to be considered when deriving the parameters from the oscillation frequency.
