摘要：
This paper presents an analytical comparison of two commonly used read-out structures for pulse oximeters, in a wearable application context. The objective is to analyze and highlight the trade-off between the SNR and the power consumption. The proposed analysis clarifies, by the means of analytical equations, the impact of the input photocurrent, the photodiode parasitic capacitance, the feedback impedance and the system bandwidth on the SNR of the two proposed front-end topologies. The paper shows that using a charge-amplifier in the front-end requires 8 times less LED power than a transresistance amplifier for achieving the same SNR.
