Abstract
An imaging device includes a pixel-circuit and a readout circuit. The pixel-circuit includes a photodetector configured to accumulate electrical charge in response to incident light and to transfer the electrical charge to a storage node. The readout circuit is configured to (i) charge a capacitance with a charge current that depends on the electrical charge in the storage node while comparing a voltage on the capacitance to a threshold, and (ii) generate an output signal indicative of a time duration needed to charge the capacitance until reaching the threshold, the time duration being inversely-related to the electrical charge accumulated by the photodetector.
