This paper presents an electrocardiograph(ECG) non-contact sensing system that compensates the high-frequency noises and the distortion due to motion artifact via two-channel interleaved electrodes in concert with proportional design and equalization algorithm. Specifically, the equivalent input capacitances of the sensing electrodes are deliberately designed to achieve a fast, low-cost, and real-time compensation signal processing. This proposed system has been implemented with a worst case of 2% unit capacitance mismatch and 25% motion artifact with a normal distribution, where the equalization can still achieve average 98.6% high accuracy.
