Abstract
A high speed analog photon counter and method is provided. In one aspect, the method includes accumulating an electric charge in a capacitor of a circuit electrically coupled to a current source. The method further includes comparing the electric charge accumulated in the capacitor of the circuit with a reference voltage through a comparator of the circuit electrically coupled to an output of the capacitor. The method also includes increasing a speed of operation of a measurement device through implementing the circuit inside a pixel. The method further includes transferring the accumulated electric charge to a circuit of an adjacent pixel and synchronizing the transfer of the accumulated electric with a movement of an object captured by an image sensor device before implementing a time-delay integration operation.
