Eliminate thermoelectric EMF in low-ohm measurements
12.07.2017 · Circuits
When two different-metal conductors connect together in a loop and one of the junctions is at a higher temperature than the other, an electrical current flows through the loop. The magnitude of this current depends on the type of metals involved and the temperature differential of the junctions. When you open such a loop, a thermoelectric voltage appears across the open ends...

Amplifier and current source emulate instrumentation amplifier
12.01.2017 · Circuits
The classic three- or two-op-amp instrumentation-amplifier circuits are standard ways to amplify a small-amplitude differential signal contaminated with high common-mode noise. In some applications, the signal source is floating with high-series-output impedance and thus requires an appropriate high-input-impedance amplifier...
