Investigation of Feedback-Controlled Biosignal Acquisition and Processing Analog Techniques for Neural Prostheses

This project tries to address one of the currently most critical problems for high-density integrated biosignal acquisition- output-associated stability regarding the low-frequency cutoff of the high-pass filtering involved in the multi-channel bioacquisition analog front end. The project will cover in depth the technical contents of literature survey, design, analysis, simulation, and implementation with system viewpoints for proposed feedback-based control circuit achieving cost-effective energy-efficient sensor(electrode)-output-associated DC offset removal. To obtain reasonable specifications taking into account the sensor- (electrode-)referred variations, using sensor(electrode) to acquire neural signals will be conducted in the project. Results of the multi-year project will include 1) how the proposed design can possess stable, wide operation voltage range, and tunable high resistance without sacrificing power efficiency and cost efficacy and 2) experimental comparison between the state-of-art works and proposed design in animal model.
