Method and apparatus for reducing dark current and hot pixels in CMOS image sensors |
摘要 |
Methods and apparatuses for reducing dark current and hot pixels in CMOS image sensors. A pixel apparatus includes a photosensor capable of generating dark current, a floating diffusion region coupled to the photosensor by way of a charge transfer transistor, a rest transistor connected between the floating diffusion region and an array pixel supply voltage. The array supply voltage varies between first and second voltages when sampling pixel signals from the pixel.
