In this work, we propose a new circuit topology for a transimpedance amplifier which allows to obtain an improved trade-off between equivalent input noise and bandwidth with respect to the conventional approach. We report a simple op-amp based circuit implementation of the new transimpedance amplifier together with the results of its noise and bandwidth characterization. The comparison between these measurements with those obtained on a conventional transimpedance amplifier has confirmed that… CONTINUE READING
