High Consistency Ramp Design Method for Low Noise Column Level Readout Chain

High Consistency Ramp Design Method for Low Noise Column Level Readout Chain

In order to address the inconsistency problem caused by parasitic backend wiring among multiple ramp generators and among multiple columns in large-array CMOS image sensors (CIS), this paper proposes a high-precision compensation technology combining average voltage technology, adaptive negative fee...
