Claim:
1. A system, comprising: a pixel array generating a plurality of output signals respectively representing radiation incident upon and stored as respective pixel charges of individual pixels in the pixel array; a selector selecting an output signal of the plurality of the output signals; and a sampler comprising a charge integrator that generates a voltage based on the pixel charge stored onto the selected pixel of the pixel array and based on a feedback capacitance of the charge integrator, wherein the charge integrator obtains a pixel charge of the selected output signal of a particular pixel onto a first feedback capacitance to produce a first sample at an output of the charge integrator, and then redistributes that pixel charge from the first feedback capacitance to a smaller second feedback capacitance to produce a second sample at the output of the charge integrator.
