In this paper, a shared-pixel architecture in which the Gr pixel and the Gb pixel are designed to have the same layout structure, is introduced for suppression of the Gr/Gb sensitivity imbalance. In addition, a more effective FD-boost scheme that uses both gate-to-source capacitance (CGS) and gate-to-drain capacitance (CGD) is introduced to resolve the trade-off between dark random noise and FD capability, without adding any additional pixel-drive wiring.
