Leakage current modeling of test structures for characterization of dark current in CMOS image sensors.

Leakage current modeling of test structures for characterization of dark current in CMOS image sensors.

In this paper, we present an extensive study of leakage current mechanisms in diodes to model the dark current of various pixel architectures for active pixel CMOS image sensors. Dedicated test structures made in 0.35-μm CMOS have been investigated to determine the various contributions to the leaka...
