Implantable biomedical chip with modulator for a wireless neural stimulation system

Abstract

The invention relates to an implantable biomedical chip with modulator for a wireless neural stimulating system. The implantable biomedical chip comprises a power regulator, a demodulator, a baseband circuit, a D/A converter, an instrumentation amplifier, an A/D converter and a modulator. According to the invention, the modulator is mounted on the implantable biomedical chip, and can achieve full-duplex communication to improve the controllability and observability. Besides, the power consumption and area occupation is reduced as compared with using discrete components. Therefore, the integration of the implantable biomedical chip can be easily accomplished.
