An image sensor is an array of small light-sensitive cells called pixel sensors. A pixel, or picture pix element el, is the smallest unit of an image. Therefore a pixel sensor is the smallest cell of an image sensor, which is able to detect a single

Charge pump circuits operating at voltage levels above that of the power supply usually suffer from gate-oxide voltage overstress. Such reliability problem has become a concern especially as the gate-oxide thickness is scaled down. Devising charge pu
