Abstract

An implantable SOC chip for micro-stimulation and neural signal recording is presented. This work possesses a multi-parameter control protocol to provide different stimulation waveforms, for various pain treatments of muscles and stimulating applications. Additionally, the proposed SOC chip supports several transmission rates of RS232, which in turn provides a flexibility to be integrated in a variety of different applications. Moreover, an IA (instrument amplifier) with CMRR of 120 dB and the stopband attenuation of 38 dB/dec is employed, which is capable of sensing very low voltage (1 to 10 muV) neural signal. The proposed design is implemented using TSMC 2P4M 0.35 mum CMOS process
