Patent abstract
Image sensors using multiple-ramp single slope analog to digital converters (ADCs) and method of their operation are disclosed. The images sensors use additional column ADCs to detect offset errors in the fine ramp signals and feedback in the analog domain to correct the errors. Averaging errors over multiple analog-to-digital conversion cycles allows for improved error correction.
