Embodiment Construction

[0110] Embodiments of the present invention will be described below with reference to the drawings.

[0111] image 3 is a block diagram showing a typical configuration of an on-a-row-ADC type solid-state imaging device (also called a CMOS image sensor) including a data transfer circuit according to an embodiment of the present invention. Figure 4 is shown included in the image 3 A block diagram of a more specific typical configuration of a data transfer system including a data transfer circuit used in the on-a-row-ADC type solid-state imaging device shown.

[0112] like Figure 13 As shown, a solid-state imaging device 10 uses a pixel array section 11 serving as an imaging section, a row scanning circuit 12, a column scanning circuit 13, a timing control circuit 14, an ADC group 15, a DAC 16, and each uses a sense amplifier (S / A ) a plurality of data output circuits (also referred to as data detection circuits) 17 of the circuit 171.

[0113] The pixel array section 11 ...

Abstract

A data transfer circuit is disclosed herein, including a plurality of data transfer lines, a plurality of data output sections, a plurality of data holding sections, a data acquisition clock supply section, a clock supply section, and a column scanning section.

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 ...
