Row driven imager pixel

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.

An imaging system, comprising:

• a driver circuit to selectively supply high and low supply voltages to a pixel array of a CMOS imager, wherein the high supply voltages are higher than the low supply voltages;
• a first pixel in a first row of pixels of the array comprising a first reset transistor coupled between the driver circuit and a first charge storage node, the driver circuit to provide a high supply voltage to the first pixel during a reset of the first pixel and to subsequently provide a low supply voltage to the first pixel to bias the first charge storage node low, and the first reset transistor to subsequently be turned off to isolate the first charge storage node before the first row of pixels is selected for readout and while a second row of pixels of the array is selected for readout;
• and
• a second pixel in the second row of pixels of the array, the second pixel to be read out while the first reset transistor remains off to isolate the first charge storage node.
