  • Patent number: 7132638
    Abstract: An imaging array having a CCD imaging array that includes a plurality of pixels that accumulate charge when exposed to light and a readout amplifier is disclosed. The readout amplifier includes an operational amplifier having an input and an output port and a feedback capacitor connecting the input and output ports and a variable impedance path between the input and output ports, the path having an impedance controlled by a reset signal. A reset signal generator generates the reset signal in three sequential phases in which the path between the input and output ports has three impedance values to provide a starting voltage at the amplifier input prior to the measurement of charge from each pixel that has reduced noise.
