Design of a Temperature-Compensated Induction Extensometer
By proper choice of materials, dimensions and circuit parameters, it is possible to design a linear displacement transducer, or extensometer, to have zero net thermal drift over any given temperature range. The chief limitation is the inability of wires and insulation to withstand very high temperatures. An extensometer has been designed and tested which could theoretically measure displacement...
متن کاملAn Adaptive String Comparator for Record Linkage
We develop a string comparator based on edit distance that uses variable edit-step costs derived from training data. Using first and last name data from Census files, we compare the performance of this string comparator with one without variable edit step costs and with the JaroWinkler string comparator, which is standardly used in the Census Bureau’s record linkage software.
متن کاملAn Automatic Dc Current Comparator Resistance Bridge
The principle of the Direct Current Comparator has been around for some 30 years, however, very little work has been done towards automation. This paper describes a bridge for measuring resistance ratios in the range of 0.001 ohms to 10,000 ohms using a microprocessor controlled automated DC Current Comparator with IEEE-488 to an uncertainty of better than 0.1 ppm from 1 ohm to 1000 ohms and 0....
متن کاملComparator-based switched-capacitor pipelined analog-to-digital converter with comparator preset, and comparator delay compensation
We present a differential comparator-based switched-capacitor (CBSC) pipelined analog-to-digital converter (ADC) with comparator preset, and comparator delay compensation. Compensating for the comparator delay by digitally adjusting the comparator threshold improves the ADC resolution from 2.5-bit to 7.05-bit. The ADC is manufactured in a 90 nm CMOS technology, with a core area of 0.85 mm 9 0.3...
متن کاملComparator Design and Analysis for Comparator - Based Switched - Capacitor Circuits
The design of high gain, wide dynamic range op-amps for switched-capacitor circuits has become increasingly challenging with the migration of designs to scaled CMOS technologies. The reduced power supply voltages and the low intrinsic device gain in scaled technologies offset some of the benefits of the reduced device parasitics. An alternative comparator-based switched-capacitor circuit (CBSC)...
