This paper describes a digital-domain self-calibration technique for multi-stage analog-to-digital converter (ADC). An accurate calibration is achieved by using a modified radixbased calculation. The equivalent radix-based error term for each stage is extracted by measuring major carry jumps from the ADC transfer curve. A new multiplying digitalto-analog converter (MDAC) architecture using (ins...

Modified least squares method (LSM) is developed that take into account errors in input standard signals for calibration of measuring devices. Calibration of the differential pressure gage by the standard control-point setting mechanisms is demonstrated in the paper as an example. The accuracy of the coefficient estimates changes when the errors of the control-point setting mechanisms are taken...

Planned offsets of the STIS Mode Select Mechanism (MSM) result in changes to the nominal calibration curves, particularly noticeable in the echelle modes. The spectral wave calibration exposures (wavecals) obtained with each observation can be used to predict a simple, linear offset of the nominal calibration curve to be used for each MSM shift. In addition, a time dependent variation has been ...
