You have designed an op-amp circuit to measure a small voltage. The circuit gain is -10V/V, but it appears that the input impedance to the circuit is effecting the device as it is being measured. How ...

You often need to measure current during circuit design and debugging. You can perform that task by breaking a path, inserting a shunt resistor, measuring its voltage, and converting the voltage to ...

Measuring dynamic currents with an oscilloscope is challenging, but this updated differential current probe makes it simple ...

All engineers know resistance is usually bad news. It generates heat. It reduces efficiency. It wears out components and cuts operational lifetimes. However, resistance is not the only kind of ...

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 ...

Oscilloscopes are one of our favorite tools for electronics development. They make the hidden dances of electrons visually obvious to us, and give us a clear understanding of what’s actually going on ...

Designs that need to measure small signals riding on high-voltage power rails suggest the use of isolation devices. However, a high-common-mode-voltage instrumentation amplifier used with a ...
