In a world first, researchers at Nagoya University in Japan have successfully developed a resonant tunnel diode (RTD) that operates at room ...

Sometimes, it's necessary to make microvolt measurements in the presence of volts. For example, the need arose to measure the thermoelectric potentials in an RTD circuit in which the 10 V applied to ...

Bridge circuits have long been popular for conditioning signals from resistive sensors. These circuits are sensitive to small changes in resistance, and they provide a differential output from a ...

This product is featured in EDN's Hot 100 products of 2017. See all 100 here. Measuring high current in circuits such as DC power supplies requires shunt resistors. Unfortunately, those resistors ...
