| Zusammenfassung: | A neural signal amplifier includes an amplifier, a switched capacitor circuit input unit, a switched capacitor feedback circuit unit, and a switched capacitor circuit output unit. The switching capacitor circuit input unit, the switched capacitor feedback circuit unit and the switched capacitor circuit output unit comprise a plurality of differential switches, a plurality of common mode switches and a plurality of capacitors. By controlling the switches to open or performing exchange capacitor operations, the signal amplifier suppresses DC drift and reconstructs the DC input of the common mode power supply. |
