Abstract
The sensitivity of logarithmic pixels at low light levels is limited by the dark current that flows through the load transistor in the pixel in parallel with the photocurrent. A new layout for a logarithmic pixel is reported that significantly reduces the dark current in the pixel. In addition a simple change to the bias voltages applied to the pixel means that the new layout can simultaneously exhibit a linear response to low-light levels and a logarithmic response at higher light levels.
