摘要： The present invention relates to a digital/analog converter. The digital/analog converter includes a divided-voltage generating section that divides a reference supply voltage through the voltage distribution; a decoder section that receives a digital signal so as to output a decoded selection signal; a first divided-voltage selecting section that selects and outputs a plurality of divided voltages among the divided-voltages generated from the divided-voltage generating section on the basis of the selection signal output from the decoder section; a second divided-voltage selecting section that selects and outputs a plurality of divided-voltages among the divided-voltages output from the first divided-voltage selecting section on the basis of the selection signal output from the decoder section; a divided-voltage storing section that charges and discharges the plurality of divided-voltages output from the second divided-voltage selecting section; a third divided-voltage selecting section that selects a predetermined voltage among the divided-voltages discharged from the divided-voltages storing section on the basis of the selection signal output from the decoder; and a voltage output section that outputs the predetermined voltage selected from the third divided-voltage selecting section.

摘要： In a CMOS image sensor of the invention, a dynamic range is varied at a per-pixel level by a light amount to prevent saturation without degrading color reproduction of an overall image. A photo diode generates charges in accordance with a received light amount. A drive transistor amplifies the charges generated in the photodiode at a given gain. Further, a saturation detector receives an output voltage from the drive transistor and judges the image sensor saturated if the output voltage is beyond a limited level. A switch switches on/off in response to the judgment of the saturation detector. Also, a plurality of floating diffusions store the charges of the photodiode transferred through the switch. The floating diffusions are selectively connected to both the photodiode and a gate of the drive transistor at on/off the switch.

摘要： The present invention relates to a data scan system and a data scan method using DDR. The data scan system includes an input section receiving data; first and second DDR memories that stores the data by using a page in which the col address increases horizontally; a DDR controller that stores the data in the first and second DDR memories or reads the stored data from the first and second DDR memories; and an output section that outputs the data read by the DDR controller. When reading the data stored in the first and second DDR memory, the DDR controller simultaneously reads at least two columns of data of the page and stores the simultaneously read data in an output buffer.
