The implantable brain-machine interface has been extensively applied in recent research. There is a little neural implant designed to record the neural spike signals, which needs a higher requirement of the characteristics. In the work, a novel signal acquisition approach for the implantable brain-machine system is presented. The system architecture is introduced including the hardware and software designs. The experiments demonstrate the designed system has successfully recorded the analog sine wave and spike signals from the signal generator and a digital neural signal simulator.
