Abstract
In accordance with an embodiment, a method of performing a successive approximation analog-to-digital (A/D) conversion includes determining a voltage range of an analog input voltage in a single cycle using a multi-bit flash A/D converter, determining an initial D/A value for a successive approximation based on determining the voltage range, and successively approximating the analog input voltage. Successively approximating includes providing the initial D/A value to a D/A converter, comparing an output of the D/A converter with the analog input voltage, and determining a further D/A value based on the comparing.
