    摘要： A method of reducing column fixed pattern noise including calibrating a readout circuit, wherein the readout circuit is electrically connected to at least one programmable gain amplifier and an analog-to-digital converter. Calibrating the readout circuit includes electrically disconnecting the readout circuit from a pixel output and electrically connecting a pixel reset input of the readout circuit to a pixel output signal input of the readout circuit. Calibrating the readout circuit further includes comparing a measured output of the readout circuit to a predetermined value and storing the comparison result in a non-transitory computer readable medium. The method further includes operating the readout circuit, the operating the readout circuit includes receiving a pixel sample signal and outputting a calibrated output based on an operating output and the stored comparison result.

    摘要： A CMOS image sensor includes a pixel array including a plurality of unit pixels with individual rows of unit pixels being coupled to respective row control signal lines, and a buffer including plural row control signal drivers. Each driver is coupled to a respective one of the row control signal lines and is configured to provide a row control signal pulse to a respective row control signal line in response to an input pulse when the row control signal line is in an active state and to bias the row control signal line at a ground voltage when the respective row control signal line is in an inactive state. Each driver has a first drive capability when the row control signal line is in the active state and a second drive capability greater than the first drive capability when the row control signal line is in an inactive state.

    摘要： An avalanche photodiode is deposited and integrated directly on top of CMOS readout circuitry. The anode of the avalanche photodiode may be independently biased at high voltage so that the avalanche photodiode may be operated in an avalanche multiplication mode. The avalanche photodiode has a multi-layered structure which is not pixilated; and photo-carrier generation and carrier multiplication may take place in the same layer or in different layers. A constant-gate-bias transistor isolates the high-voltage avalanche photodiode from the low-voltage the CMOS readout circuitry.
