  • Patent number: 6933974
    Abstract: A CMOS image sensor that outputs signal data before outputs reset data, and a driving method therefor. The CMOS image sensor includes a pixel sensor, a data I/O line, a double sampling circuit and an output circuit. The pixel sensor generates signal data and reset data. The signal data has a voltage level depending on an amount of photo-charge produced in response to energy received externally. The reset data is produced in a reset mode. The data I/O line transfers the generated signal data and the reset data. The double sampling circuit samples the signal data and then the reset data, from the data I/O line, and drives an output terminal. The output circuit outputs data related to a voltage level of the output terminal.

  • Patent number: 6621109
    Abstract: A charge coupled device includes a plurality of photoelectric conversion regions; a plurality of vertical charge coupled devices (VCCDs) provided between the photoelectric conversion regions for transmission of charges generated at the photoelectric conversion regions in a first direction; and a horizontal charge coupled device (HCCD) coupled to the VCCDs and having a channel region including a plurality of channels for transmission of the charges previously transmitted through the VCCDs in a second direction. The channel region is formed such that one of the plurality of channels has a higher potential than the remaining channels. The remaining channels have potentials that gradually become lower than the highest potential moving in a direction away from the channel with the highest potential. The channel region transmits the charges within the HCCD so that the charges are gathered together centered around the channel having the highest potential during transmission of the charges.

  • Patent number: 6570144
    Abstract: An active pixel circuit in a CMOS image sensor includes a photodiode to accumulate charge due to incident light. A first transfer transistor is arranged to pass a transfer signal when turned on by a column selection signal. A second transfer transistor transfers the accumulated charge from the photodiode to a first floating node when turned on by the transfer signal from the first transfer transistor. A source follow driver transistor changes the potential of a second floating node according to the charge transferred to the first floating node. A line selecting transistor reads out the potential of the second floating node when turned on by a line selection signal, and a reset transistor resets the charges accumulated in the first floating node when the reading out operation is finished.
