Abstract
In certain embodiments, a system is provided for image capture that includes a unit cell that includes a Capacitor TransImpedance Amplifier (CTIA) subcircuit, a Source Follower per Detector (SFD) subcircuit, and a Direct Injection (DI) subcircuit. The unit cell may operate using one of the subcircuits selected in response to a control signal. A column amplifier may be coupled to the unit cell. The column amplifier may be operable to receive an intermediate signal from the unit cell and couple components of the column amplifier corresponding to the selected subcircuit in response to the control signal. The column amplifier may generate an output signal from the intermediate signal using the coupled components of the column amplifier.
