【 摘 要 】

We present a novel bandwidth enhancement technique for a transimpedance amplifier (TIA). The proposed TIA utilizes a common source topology and adopts the current mirror configuration using flipped voltage follower to increase the open-loop gain for the enhanced bandwidth with positive feedback. Circuit simulation results show that the proposed TIA makes it possible to increase the open-loop gain and enlarge the bandwidth by 40% compared with the conventional TIA.
