Heart disease is one of the most important causes of death around the world. To monitor and react to the condition of the patients in time and efficiently, ECG technology is rather essential because it not only has low cost and simple operation, but also can get results quickly. In order to capture the original differential signals produced from human body and suppress the electromagnetic interference, this paper has designed a differential amplifier which can apply subtraction to the original signals and amplify them to get a clear ECG signal. The circuit has been designed with 0.18 μm CMOS process. The plot of simulation results show that the total current consumption of the circuit is controlled to be 19 μA and the differential gain and the common mode gain are correspondingly 40.76 dB and -42.36 dB. According to the simulation result of ECG in this paper, the electromagnetic interference has been rejected and the acquired signal is amplified to be essay to observe. Such an ECG technology has a very positive effect on cardiovascular disease treatment.
