Classification: CPC G  H | IPC H

Claim 12:
13. A method of operation within a sensing device, the method comprising:
storing, using a photodiode, two or more electrons within a photowell of the photodiode in response to light reflected from a surface;
generating, using readout circuitry, an output signal that transitions between voltage levels in response to storage of each of the electrons within the photodiode;
generating, using a counter, an incremental sequence of count values;
storing, a plurality of latching circuits receiving respective input signals that are generated based on the output signal, respective count values of the incremental sequence when the respective input signals exceed respective threshold levels; and
generating, using a measurement circuitry, a value representative of a distance between the sensing device and the surface based on the stored count values of the latching circuits.
