Abstract:
1. A CMOS image sensor, comprising: a pixel array comprising a plurality of unit pixels arranged in a plurality of rows and columns, individual rows of unit pixels being coupled to respective row control signal lines; and a buffer comprising a plurality of row control signal drivers, each row control signal driver being coupled to a respective one of the row control signal lines, each row control signal driver 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 said row control signal line at a ground voltage when the respective row control signal line is in an inactive state, wherein each row control signal 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.
