Abstract: The key of using a sensor to detect electrocardiosignal (ECG) is on extracting a weak signal from strong noise background and performing the high-gain amplification. The ECG characteristics and circuit model were analyzed in this study. The design included the detection sensor of four parts-preamplifier, high-pass and low-pass filter circuits, 50 Hz notch filter and main amplifier, and the sensor has a high common-mode rejection ratio (CMRR) and uses a special chip UAF42 to filter power frequency interference. It has been successfully applied to the ECG monitoring system to achieve good results.
Keywords: ECG, Driving circuit of right leg, Filter.
