基于ADS1298的表面肌电采集系统设计

Design of surface electromyographic signal acquisition system based on ADS1298

针对现有表面肌电信号采集方法存在的元器件较多、电路复杂和调试困难等问题,以ADS1298集成模拟前端设计了一种新型s EMG信号采集系统.通过充分利用ADS1298集成的可编程增益放大器、24位高分辨率ADC以及右腿驱动放大器,简化了前端调理电路的设计,使系统的集成度高、体积小、功耗低.

For the problems of the usually used surface electromyography （sEMG）signal acquisition method such as too many components, circuit is too complex and difficult to debug, a new type of sEMG signal acquisition system was designed by using the integrated analog front-end ADS1298. The design of front-end conditioning circuit are simplified by fully using the programmable gain amplifier （PGA） which is integrated by ADS 1298, 24 bits high-resolution analog-to-digital converter （ADC） and right-leg-driven amplifier, and the system has high integration, small size and low power consumption.
