A 0.75-mW analog processor IC for wireless biosignal monitor

This work presents a single-channel analog processor IC for the wireless biosignal monitor. This chip occupies a small die area of 0.52 mm/sup 2/ and has a low power consumption of 0.75 mW at a 5-V supply voltage. The wired and wireless systems constructed by using the designed processor chip and commercial discrete lCs have been validated in this study. Experimental results indicate that the integrated single-chip processor system can amplify, filter, transmit, and receive the simulated ECG signal. Compared to the wired prototype system, wireless transmission provides better long-distance, long-term measuring, recording, and monitoring the biosignal.
