The old saying “if it ain’t broke, don’t fix it” cautions against tampering with something that performs reliably and regularly proves its worth. Arguably, this advice applies to the circuit design ...

Traditionally, resistance-temperature-detector (RTD) sensor resistance is measured by applying a precision current source and measuring the developed voltage. This approach usually ...

An earlier Design Idea described how to linearize the output of an RTD (resistance-temperature-detector) sensor and how to calculate the resistor values using a spreadsheet (Reference 1). That idea ...
