ABSTRACT:

BACKGROUND
In an image sensor, data is produced in output. Sometimes, it is desirable to be able to do various things with the data. Sample and hold units often obtain the information, and output the information as necessary.
SUMMARY
It is an object of the present system to define a circuit that enables reading out pixel data at the same time as analog conversion is occurring. The present system describes the circuit which enables conserving and reading out previous conversion while doing a new conversion.
