A novel operation scheme that realizes a combined linear-logarithmic response in conventional photodiode-type (PD) three-transistor (3-Tr) active pixel sensor (APS) cells is presented. It has been revealed that, by setting a reset transistor in weak inversion through properly selected bias voltages, conventional PD 3-Tr APS cells can be operated with a seamlessly combined linear-logarithmic response. A modification in the conventional APS cells that enhances their dynamic ranges in a linear response mode is also described.
