    Abstract

    Chopped neural front-ends allow the combination of low-noise performance and low area consumption, making them a favorable topology in low-noise, massively parallel recording systems. The decrease in input impedance is commonly counteracted by boosting schemes utilizing precharging buffers, that can lead to unwanted residual charge transfer to the electrodes or external DC blocking capacitors, which might be harmful for electrodes or saturate the input over time. To compensate for these charges and to avoid charge accumulation, an internally modulated buffer topology is presented.
