Abstract
Dual conversion gain pixel methods, system, and apparatus are disclosed. Dual conversion gain may be obtained by configuring an active pixel having a storage node, a first connection region, a second connection region, and a capacitor coupled between the storage node and the second connection region to introduce a first conversion gain by connecting the first connection region to a power source and connecting the second connection region to a current bias source and reconfiguring the active pixel to introduce a second conversion gain by connecting the second connection region to the power source and connecting the first connection region to the current bias source.
