ABSTRACT:
Under an embodiment, a system includes an array of analog photocells; a first plurality of shift cells, each shift cell in the first plurality of shift cells being coupled to a corresponding analog photocell; and a second plurality of shift cells, each shift cell in the second plurality of shift cells being coupled to a corresponding shift cell in the first plurality of shift cells; and a differential operational amplifier having a first input coupled to a terminating output of the first plurality of shift cells and a second input coupled to a terminating output of the second plurality of shift cells.
