CMOS Cascade Sigma-Delta Modulators for Sensors and Telecom: Error Analysis and Practical Design contains highly valuable information that is structured to give the reader the necessary insight on how to design SC sigma-delta modulators.
Authors: Río Fernández, R., Medeiro Hidalgo, F., Pérez-Verdú, B., Rosa Utrera, J.M., Rodríguez-Vázquez, Á. CMOS Cascade Sigma-Delta Modulators for Sensors and Telecom: Error Analysis and Practical Design starts with a tutorial presentation of the fundamentals of low-pass sigma-delta modulators, their applications, and their most common architectures.
To guide in selection of method and operating conditions, and in design of the sensor, we performed an error analysis.
Theoretic precision and testing error analysis of the sensor has been pursued at the end of the paper.
We report the design, fabrication and error analysis of a sun sensor array composed of six photodiodes.
Based on modeling and error analysis, stochastic error of inertial sensor, measurement noise, modeling error and environmental disturbance are formulated into different types of disturbances described by a Markov stochastic process, Gaussian noise and a norm-bounded variable, respectively.
Finally, this method of analysis is robust to BG sensor error.
The error analysis further indicated that the inertial sensor drifted approximately 6° at the beginning of a trial during the initialization.
For the per-protocol analysis, data from OCL nights during which there were technical problems such as infusion set failure, sensor error >20%, or pump failure resulting in a >60-min interruption to closed-loop control were removed to allow for analysis of algorithm performance.
Theory and error analysis.
