Front-end amplifier of low-noise and tunable BW/gain for portable biomedical signal acquisition
2008
2008 IEEE International Symposium on Circuits and Systems
We proposed a novel analog circuit design which is suitable for various biomedical signal acquisitions. In addition to the consideration of low power and low noise, the analog front-end integrated circuit (AFEIC) is presented with design of high common-mode rejection ratio (CMRR) and high power supply ripple rejection ratio (PSRR). It has not only reduced the number of outer components, and enhances a better signal-to-noise ratio (SNR). The chip includes a current-balancing instrumentation
