Abstract: A circuit may include a first sample node configured to provide a low precision sample of an input signal, a second sample node configured to store a high precision sample of an input signal, and a first switch circuit coupled between an input and the first sample node. The circuit may further include a second switch circuit coupled between the first sample node and the second sample node and configured to limit leakage current that could discharge the second sample node.
