Reliability Enhancement of Analog-to-Digital Converters (ADCs)
Reliability of systems used in spa e, avioni and biomedi al appli ations is highly riti al. Su h systems onsist of an analog front-end to olle t data, an ADC to onvert the olle ted data to digital form and a digital unit to pro ess it. The reliability of these systems is a e ted by the ability of its onstituent blo ks to tolerate faults. Therefore, it is ne essary to in rease the reliability of...
متن کاملImproving adaptive resolution of analog to digital converters using least squares mean method
This paper presents an adaptive digital resolution improvement method for extrapolating and recursive analog-to-digital converters (ADCs). The presented adaptively enhanced ADC (AE-ADC) digitally estimates the digital equivalent of the input signal by utilizing an adaptive digital filter (ADF). The least mean squares (LMS) algorithm also determines the coefficients of the ADF block. In this sch...

Reliability of systems used in spa e, avioni and biomedi al appli ations is highly riti al. Su h systems onsist of an analog front-end to olle t data, an ADC to onvert the olle ted data to digital form and a digital unit to pro ess it. It is important to analyze the fault sensitivities of ea h of these to e e tively gauge and improve the reliability of the system. This paper addresses the issue...
متن کاملDigital Calibration and Correction Methods for CMOS Analog-to-Digital Converters
Along with the miniaturization of CMOS-LSIs, control methods for LSIs have been extensively developed. The most predominant method is to digitize observed values as early as possible and to use digital control. Thus, many types of analog-to-digital converters (ADCs) have been developed such as temperature, time, delay, and frequency converters. ADCs are the easiest circuits into which digital c...
