A TRANSDUCER INTERFACE FOR RESISTIVE SENSOR ELEMENTS BASED ON THE USE OF A FLIP-FLOP<br />

Journal Title: Metrology and Measurement Systems - Year 2005, Vol 12, Issue 1

Abstract

This paper presents a new transducer interface. This interface serves the resistive bridges. The A/D conversion is based on the use of an auto-compensatory system with two digital-to-analog converters (DACs). A new measurement technique based on the use of a flip-flop circuit is used to obtain high accuracy. The main advantages of the depicted architecture are: a) Calibration accuracy depends only on LSB and maximal differential non-linearity (max(DNL1)) of the first digital-to-analog converter (DAC). b) Resultant accuracy of measurement depends on calibration accuracy and on accuracy of the second DAC. c) Calculation of a correction formula (or look up table) and input amplifier are not required. The experimental measurement circuit with flip-flop was constructed and simulated to verify operation of the measurement.
