A unit cell includes a MOSFET and an integration capacitor. The MOSFET includes a source, a drain, and a gate. The drain is coupled to the source, and the MOSFET is operable to store a first portion of an electric charge corresponding to a detected light intensity. The integration capacitor includes a first end and a second end. The first end is coupled to the drain of the MOSFET and the second end is coupled to a ground. The integration capacitor is operable to store a second portion of the electric charge corresponding to the detected light intensity.
