Low noise, analog electrocardiogram signal amplifier for wearable equipment

Due to the rapid development of semiconductor technology, the edges of electronic devices are getting smaller and the power consumption is getting lower and lower 3-op-amp instrumentation amplifier. However, there are still some problems such as excessive power consumption and noise. First, the disadvantages are identified, and then the shortcomings of the specialty are improved. So this design gives a low noise ECG equipment, which shows great performance in reducing noise to 3.94uV and the highest differential gain reaches 36.508376dB. It can be used in watches and other wearable devices for ECG signal detection. At the same time, this project can complete the required requirements and is suitable for some wearable devices. Its successful research could lead to more accurate ECG monitoring and consume less power in wearable devices. More importantly, its emergence brings new development ideas and development directions to ECG equipment, making ECG monitoring convenient and mobile.
