Conventional image sensors are mainly rolling-shutter continuous CMOS image sensors that repeat exposure and read-out signals quickly for every frame [1]. A global shutter is a necessity in this field because objects move very fast. Recently, global shutter CMOS image sensors with column-parallel ADCs [2] or analog parallel-output circuits [3] have been reported. A higher frame rate can be achieved by reducing the number of pixels. Consequently, the read-out speed, namely the frame rate times the number of pixels, is limited at around 10Gpixel/s in the conventional global-shutter CMOS image sensors. To
