Abstract
A method for providing an improved active pixel sensor cell having a soft-saturation circuit. The method includes providing a pixel node and a photodiode coupled to the pixel node. The photodiode receives light and converts the light into an electrical signal representative of light. A soft-saturation circuit for selectively affecting the electrical signal at the pixel node based on the electrical signal at the pixel node based on the electrical signal at the pixel node is also provided.
