Abstract
A detection circuit that may include (i) a photosensor that is configured to convert light to current; wherein the photosensor has an output node and is configured to operate as a current source, (ii) an adder, and (iii) multiple amplification branches that are coupled in parallel between the adder and the output node of the photosensor. The multiple amplification branches do not share a feedback circuit, wherein all amplification branches of the multiple amplification branches comprise an amplifier of a same type, wherein the type is selected out of a transimpedance amplifier and a current amplifier.
