1. A method comprising:

  • allowing light to be incident upon a photodetector circuit to thereby generate an input signal representing the light, the input signal being applied to a gate of a first field effect transistor (FET);

    applying a first control signal to a drain of the first FET and thereby generating an output current at a source of the first FET; and

    accumulating charge in a capacitor coupled to the source of the first FET.
