Abstract
An imaging device includes a pixel-circuit and a readout circuit. The pixel-circuit is configured to (i) transfer a reset charge of a photodetector to a storage node upon being reset, (ii) generate a reset output voltage according to the reset charge, (iii) accumulate electrical charge in the photodetector in response to incident light, (iv) transfer the accumulated electrical charge to the storage node, and (v) generate a pixel output voltage according to the accumulated charge stored in the storage node. The readout circuit is configured to (i) during a setup phase, charge a capacitor according to the reset output voltage, and (ii) during a measure phase, discharge the capacitor, and measure a discharge time until the charge on the capacitor is according to the pixel output voltage.
