Assignee: CHENGDU IMAGE DESIGN TECHNOLOGY CO. LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 1:
2. The read circuit for the image sensor according to claim 1, wherein the first analog-to-digital conversion unit comprises the switched capacitor array, a comparison module, and a control logic module, wherein
the control logic module is electrically connected to the switched capacitor array to control a polar plate voltage of the switched capacitor array;
a first input end of the comparison module is electrically connected to the switched capacitor array;
a comparison reference voltage is input at a second input end of the comparison module so as to be compared with a voltage signal input at the first input end of the comparison module; and
an output end of the comparison module is electrically connected to the control logic module to output the high-bit conversion data via the control logic module.
