We carry out a detailed noise analysis on a four-quadrant CMOS imager and the external hardware. Careful analysis reveals several design issues on the printed circuit board (PCB). We propose solutions to improve the PCB design. Experimental results show the modified system outperforms the original one with a sizable marginenA-SeCMOS ImagerMaster Thesis
