Abstract:
1. A method, comprising: providing a first supply voltage to a channel terminal of a first reset transistor of a first pixel in a first row of pixels of a pixel array while the first reset transistor and a first transfer transistor of the first pixel are on; subsequently providing a second supply voltage, lower than the first supply voltage, to the channel terminal of the first reset transistor while the first reset transistor is on and the first transfer transistor is off; subsequently turning off the first reset transistor to isolate a floating diffusion node coupled to the first reset transistor in a low state; and subsequently, while the first reset transistor remains off and the floating diffusion node is isolated in the low state, reading out a second pixel in a second row of pixels of the pixel array.
