Design of the Pulse Oximetry Measurement Circuit and Its Sensing System Based On CMOS
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2017, Vol 12, Issue 1
Abstract
The pulse oximetry circuit and its sensing system is designed based on the standard CMOS technology of 0.18um. The reflection oxygen sensor is used to collect the pulse oximeter signal of human body, then the collected physiological signals are processed by the data processing circuit The data processing circuit is composed of two parts: the amplifying circuit and the band-pass filter circuit, and the pulse oximeter data processed by the data processing circuit is written into the tag through the SPI communication The RFID reader read the data in the RFID tag through wireless communication, and display the data . The experimental results show that the maximum error is ±1%. The maximum error of the pulse is ±1.9%. The stability and feasibility of pulse blood oxygen sensing system is demonstrated in this paper and it will have a good application prospect in the direction of wearable medical wisdom research.
