Synthesis and Analysis of Low Power and High Speed Translinear Circuits for the Linearization of Sensors

Abstract

In real-world scenarios, the accurate measurement of physical and electrical newlinequantities is paramount for the progress of scientific, and technological domains. newlineA dependable measurement system serves as a benchmark, facilitating the comparison of unknown values with established reference standards. However, the precision newlineof electrical transducers in quantifying physical quantities can face challenges, such newlineas offset, gain, and non-linearity. As a result, experts in measurement and control newlineadvocate for devices that exhibit either an exact linear input-output relationship or a newlineclosely approximate linear transfer function. It minimizes the necessity for complex newlinenon-linear calibration curves when determining the actual value of the measured newlinequantity or presenting it directly. newlineImproving the precision and sensitivity of sensors and transducers by reducing newlinetheir inherent non-linearity is paramount in contemporary process industries. Factors like material degradation, aging, wear, saturation, and hysteresis can all impact the linearity of sensors. Current techniques, well-documented in academic newlineliterature, show promise in enhancing sensor linearity and reducing non-linearity. newlineHowever, when implemented in real-time scenarios through microcontrollers, fieldprogrammable arrays, and OP-AMP-based analog circuits, these methods often encounter challenges such as high power consumption, prolonged computation times, newlineand high error rates. newlineThis research aims to reduce non-linearity in temperature sensors by employing linear and non-linear functions referenced in the current literature, using a newlineTranslinear-based Application-Specific Integrated Circuit. newline
