A 10 Gb/s noise-canceled transimpedance amplifier for optical communication receivers

This study presents a noise-canceled transimpedance amplifier (TIA) for optical receivers. The proposed structure consists of a shunt feedback common source amplifier as an input stage followed by two regulated cascodes (RGC) and finally a differential to the single-ended amplifier at the output stage. By exploiting the noise-canceling technique at the input stage, 31.8
