Description

technical field [0001] The present invention relates to a data transmission circuit, a solid-state imaging device typified by a CMOS image sensor, and a camera system. Background technique [0002] In recent years, CMOS image sensors have attracted attention as solid-state imaging devices used as image sensors replacing CCDs. [0003] This is because special handling is required in constructing the CCD pixel, and in addition, multiple power supply voltages are required in order to operate the CCD pixel. Based on this, in the case of a CCD, it is necessary to combine a plurality of peripheral chips and operate the chip. A CMOS image sensor is therefore used as a sensor for solving various problems each arising in a CCD pixel-based system as a problem that complicates the system. [0004] CMOS image sensors can be constructed using the same manufacturing processes as those used to construct general CMOS integrated circuits. In addition, a CMOS image sensor can be driven by ...
