Classification: CPC H | IPC H

Claim 11:
12. A system, comprising:
the integrated circuit of claim 1, further comprising a pixel that comprises the photodetection region, the charge storage region, the readout region, and the drain region; and
a control circuit electrically coupled to and configured to operate the pixel to, in response to each of a plurality of pulses of excitation light that illuminate a sample:
transfer, from the photodetection region to the drain region, charge carriers generated in the photodetection region in response to the photodetection region receiving the excitation light;
aggregate, in the charge storage region, from each pulse of the excitation light, charge carriers generated in the photodetection region in response to the photodetection region receiving fluorescent light emitted by the sample; and
transfer, from the charge storage region to the readout region, following the plurality of pulses of excitation light, the aggregated charge carriers.
