Abstract
Techniques to provide automatic-gain ranging for high dynamic range by including a separate S/H capacitor, segmenting the S/H capacitor into a plurality of capacitors, and determining the number of segments to use for a sample. In this manner, the size of the S/H capacitor can be changed (by adjusting the number of capacitors), which can change the amount of input voltage that produces an amount of charge. Using these techniques, the full-scale input range for a sample of the analog input signal can be adjusted automatically based on the magnitude of the sample, which can provide better resolution and/or better noise performance for that particular sample then would otherwise be possible.
