A wide-dynamic-range photodiode-type (PD) active pixel sensor (APS) cell with seamlessly combined logarithmic–linear–logarithmic response is proposed for the first time and its operation is verified by circuit simulation. It has two additional metal–oxide–semiconductor field-effect transistors (MOSFETs) stacked in parallel to the reset MOSFET of conventional three-transistor (3-Tr) PD APS cells. By utilizing our previously proposed operation scheme that achieves automatic linear–logarithmic response switching, the proposed 5-Tr APS cell realizes seamlessly combined logarithmic–linear–logarithmic response.
