Image sensor with noise reduction

Systems and methods are disclosed for reducing reset noise in an image sensor. Voltage on the column read out is sensed during reset. When the voltage reaches a desired threshold level, a voltage is asserted on the column read out line that turns off the reset transistor. Using column circuitry to turn off the reset transistor may be used to reduce noise associated with the reset switch. In example embodiments, a comparator may be included on each column line to determine when the threshold voltage has been reached and to trigger the assertion of the turn off voltage on the column line.
