Abstract
We propose a new method for canceling the fixed-pattern noise in CIVIOS image sensors caused by the threshold mismatch of MOSFETs in pixel circuits. This method uses non-destructive intermediate readout circuitry. We designed a CMOS image sensor in which the canceling circuit was implemented in each column of the pixel-sensor array using a 0.25μm CMOS process. Results from simulations and actual measurements taken revealed that our method would be effective in canceling fixed-pattern-noise in CIVIOS image sensors caused by the threshold mismatch.
