Comparison of linear and non-linear equations for univariate calibration.
Univariate data accumulated for the purpose of calibration of chromatographic and spectroscopic methods often exhibit slight but definite curvature. In this paper the performance of a non-linear calibration equation with the capacity to account empirically for the curvature, y = a + bx(m), (m not equal to 1) is compared with the commonly used linear equation, y = a + bx, as well as the quadrati...
متن کاملMathematical Model of Unsteady Groundwater Flow Through Aquifers and Calibration Via a Non-Linear Optimization Technique
In this study, the general partial differential equation of unsteady groundwater flow through non-homogeneous and anisotropic aquifer was solved by the fully implicit finite difference method with control volume approach. The calibration of permeability and storage coefficients as model parameters was performed by a transformation technique and application of Powell's non-linear optimization me...

15 صفحه اولDigital Calibration Incorporating Redundancy of Flash ADCs
As feature size and supply voltage shrink, digital calibration incorporating redundancy of flash analog-to-digital converters is becoming attractive. This new scheme allows accuracy to be achieved through the use of redundancy and reassignment, effectively decoupling analog performance from component matching. Very large comparator offsets (several LSBs) are tolerated, allowing the comparators ...
متن کاملNon-Linear Model Based Calibration of D/A Converters
Various error sources cause linearity errors which degrade the performance of D/A converters. The paper presents a non-linear model to describe multiplying D/A converters. A Walsh transformation based diagnostic tool is used to determine the model parameters. Based on this model, a calibration scheme is derived, in order to compensate the non-linear behaviour of the converter. Practical applica...
