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 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 ICs 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.
