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 ...

Terahertz wireless has long sounded like the next big leap; fast enough to move huge amounts of data with less delay. Yet the hardware has struggled to keep up. A key part, the resonant tunnel diode, ...

Designing an analog circuit can be a frustrating experience, as noted by Nick Cornford in his Design Idea (DI), “DIY RTD for a DMM.” With a fortnight’s struggle, I completed the design of 4 mA to 20mA ...

The TTM series provide a 4-20 mA output using an integrated PT100 resistance temperature detector. TTM series sensors are plug-and-play, and come pre-scaled at 0 to 100 degrees C, 0 to 150 degrees C, ...

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