A DAC Mismatch Calibration Technique for Multibit Sigma Delta Modulators

Pierre-André Farine, Steve Tanner, Shafqat Ali

A technique for the calibration of DAC (digital to analog converter) mismatch errors in multi-bit Sigma Delta modulators (SDM) is presented. It consists of two parts: the first is a measurement technique to obtain the relative mismatch of each feedback DAC ...

Wireless GPS-based phase-locked synchronization system for outdoor environment

Alexander Bahr, Frédéric Meyer, Thomas Lochmatter

Synchronization of data coming from different sources is of high importance in biomechanics to ensure reliable analyses. This synchronization can either be performed through hardware to obtain perfect matching of data, or post-processed digitally. Hardware ...

Compensation of the Instrumental Decay in Measured Lightning Electric Field Waveforms

Farhad Rachidi-Haeri, Marcos Rubinstein, José-Luis Bermudez

The proper characterization of lightning electric and magnetic fields is very important for a number of reasons, such as the study and design of lightning protection and the validation of return stroke models. Also, an accurate late time response of the se ...

Methodology for the Digital Calibration of Analog Circuits and Systems Using Sub-binary Radix DACs

Maher Kayal, Marc Pastre

This paper presents a methodology for digitally calibrating analog circuits and systems. Based on the detection of an imperfection by a simple comparator, a successive approximations algorithm tunes a compensation current. The latter is generated by a sub- ...
