基于CMOS工艺的脉搏血氧测量电路设计
Design of pulse blood oxygen measurement circuit based on CMOS
摘要
Abstract
In order to avoid the high power consumption and large noise of the transmission measurement system,a CMOS integrated circuit to measure the pulse and blood oxygen saturation is designed. The measurement circuit is composed of two parts:the amplifier circuit and the band-pass filter circuit.After the processing of the measured circuit,the DC quantity and AC quantity of the pulse wave are obtained.Using CMOS standard of UMC 0.18 μm process,the circuit simulation of the parameters are as follows.With the operating voltage of 1.8 V,the gain of the whole system can reach 42-50 dB, the power consumption of the whole system is less than 0.3 mW. Therefore,the gain of the measurement circuit achieves the requirements,and noise and power consumption are smaller,more able to achieve the development of portable medical equipment requirements.关键词
