Description

This paper presents the performance characteristics of a new active pixel sensor (APS) structure based on a linear-logarithmic response, which is implemented using a 0.35-μm standard CMOS process. The new pixel structure allows tuning of the dynamic range and the sensitivity. At the low-intensity light, both the dynamic range and the linear sensitivity were improved due to the increased capacitance of the photodetector. At the high-intensity light, the pixel is operated in a logarithmic mode by an additional MOSFET. Furthermore, the reference voltages can adjust the sensitivity and the starting point of logarithmic response.
