Patent attributes
Various embodiments of the present invention provide systems and circuits that provide for conversion of analog signals to digital signals. For example, various embodiments of the present invention provide methods for performing analog to digital conversions that include providing an analog to digital converter with a residue amplifier that is associated with a first capacitance set that includes a first feedback capacitor and first set of input capacitors, and a second capacitance set that includes a second feedback capacitor and second set of input capacitors. The methods further include performing a first sample of an analog input voltage by charging the first set of input capacitors from the analog voltage input during a first period; amplifying the first sample during a second period; performing a second sample of the analog input voltage by charging the second set of input capacitors from the analog voltage input during a third period; and amplifying the second sample during a fourth period.
