碩士 === 中華大學 === 電機工程學系(所) === 98 === Abstract This thesis contains two major parts. One is the portable multi-lead ECG recorder. It can be applied to telemedicine, healthcare at home, and course record of disease. Satisfy the demand for modern personal health management. Another is multi-lead ECG analog front-end IC design and pre-simulation. In the future, we may assemble a multi-lead ECG measurement system on a chip with the multi-lead ECG analog front-end circuit, analog to digital converter, and an embedded processor core. The proposed portable multi-lead ECG recorder can process three leads ECG signal simultaneously. It is a low-cost and low-power solution. For the ECG analog front-end circuit, we base on operation amplifiers to construct instrument amplifiers, band-pass filters, post-amplifiers, and offset circuits. For the microcontroller, we use Microchip PIC24FJ128GB106 that embed multi-channel analog to digital converter, serial peripheral interfaces, and a USB interface. When the device is acting alone, ECG data store to a memory card. When the device connects to the personal computer by USB, real-time ECG waveforms can be shown on the screen. Besides, the ECG data that have been stored in memory card can be transmitted and displayed by the personal computer. The planned multi-lead ECG analog front-end IC is based on TSMC 2P4M 0.35um CMOS process. At present, the circuit design and pre-simulation is completed. Next, we may construct a multi-lead ECG measurement system on a chip with this multi-lead ECG analog front-end circuit, a multi-channel analog to digital converter and an embedded processor core. In the future, the proposed portable multi-lead ECG recorder will involve abnormal detecting capability, and contain wireless communications. It can be applied to the prevention and treatment of the heart related disease, for personal health management and healthcare at home.
