Abstract
The paper presents detailed trade-offs encountered in the design of low-power integrated pulse oximeters (PO). The significance and interdependence of parameters such as the switching frequency, duty cycle, settling speed, stability and capacitor area and their role in system power and noise are discussed thoroughly. Quantitative relations between these parameters are derived and numerical examples with typical values given.
