Abstract: 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.

Abstract: A current steering digital-to-analog converter (DAC) is provided. At least two lower-resolution DACs are used for converting a high-resolution digital signal. One of the two lower-resolution DACs is used for converting the most significant bits (MSB) of the high-resolution digital signal. The other of the two lower-resolution DACs is used for converting the least significant bits (LSB) of the high-resolution digital signal. By such arrangement, a device mismatch problem is avoided and the chance of variation occurrence during manufacturing process is reduced. The arrangement also simplifies the layout in the significantly scaled-down chip area.
