Abstract
A high dynamic range amplifier circuit for amplifying pixel signals of an imager device is disclosed. The amplifier circuit uses a read-out scheme based on a charge recycling approach, where a pixel signal is first amplified with a low gain during a first amplification phase T, and then the amplifier output is immediately recycled and the pixel signal amplified with a higher gain during a second amplification phase T
