| Summary: | 碩士 === 國立雲林科技大學 === 電子與資訊工程研究所 === 100 === Heart disease is in second place among the top 10 causes of mortality in Taiwan. To reduce Heart disease-related mortality rate, it is important to receive therapeutic assistance within the golden hour. This study designed a frequency to voltage convertor chip (FVC) that can change the output voltage signals of the convertor according to the characteristics of frequency alternation. When applied in heart-rate detection, the chip can deliver immediate warnings to users when heart-rate abnormality is detected. The chip can be applied in heart rate detection to check the rate of heartbeats, and the detecting results are demonstrated on four LEDs for users to know whether their heart rates are abnormal.
The study applied TSMC 0.18UM CMOS 1P6M 1.8&3.3V process to complete chip design. In the initial circuit design, peripheral circuits were applied along with the frequency to voltage convertor chip for system testing. Then in the second circuit design, peripheral circuits were involved in the chip to complete a portable heart rate detecting and warning system.
