Abstract
A sampling circuit for dynamic imaging is provided. Specifically, embodiments of the present invention relate to a readout integrated circuit (ROIC) for dynamic imaging and a related image sensor. In one embodiment of the present invention, a sampling circuit is provided that comprises: an amplifier circuit, which amplifies charge signals generated at photo diodes and converts them to voltage signals; a filter circuit (optional) that receives and filters the voltage signals to yield a filtered signal; a sampling circuit, which samples the voltage signals and outputs a sampled signal in accordance with a sampling control signal; and a digital converter, which converts the sampled signal into a digital format and outputs a digital signal.
