Journal ArticleDOI
A Novel Calibration-Free Method of Measurement of Oxygen Saturation in Arterial Blood
TL;DR: A novel method of computation of SpO2 that does not require the use of a calibration curve is presented, based on a model for the attenuation of light through skin, tissue, bone, and blood, that becomes free of not only patient but sensor-dependent parameters as well.
Journal ArticleDOI
A Novel Dual-Slope Resistance-to-Digital Converter
TL;DR: A dual-slope resistance-to-digital (DSRDC) converter that accepts the resistance of a single-element resistive-type sensor as input and provides a direct digital output proportional to the parameter being sensed by the resistive -type sensor is presented.
Journal ArticleDOI
Analysis of a Sigma–Delta Resistance-to-Digital Converter for Differential Resistive Sensors
TL;DR: A direct resistance-to-digital converter (RDC) that is suitable for differential resistive sensors is proposed and analyzed and shows that the proposed RDC has negligible sensitivity to variations in circuit parameters.
Proceedings ArticleDOI
Digital Converter for Push-Pull Type Resistive Transducers
TL;DR: In this paper, a direct RDC suitable for push-pull type resistive transducers is proposed, which forms an integral part of an integrating type analogue-to-digital converter and provides a digital output proportional to the physical quantity being sensed.
Proceedings ArticleDOI
Dual Slope Resistance to Digital Converter
TL;DR: In this article, a dual slope digital converter for differential resistive sensors is presented. But the output is decided only by a pair of dc reference voltages and the transformation constant of the sensor.
