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

A version of thie article appeared in the February 2012 issue of Test & Measurement World. See the PDF. Many industrial systems use the 4–20-mA loop to transmit measurements from sensors to displays, ...

In switched-mode power supplies (SMPS), magnetic components, namely inductors and transformers, play critical roles. Much of the SMPS design process relies on component specifications and simulation ...

A wide common mode input voltage range, from ground to within 2V of the supply voltage, ensures that the ZXCT1050 current monitor from Zetex Semiconductors will continue to provide accurate current ...

Current sensing is used to perform two essential circuit functions. First, it is used to measure “how much” current is flowing in a circuit, which may be used to make decisions about turning off ...

STMicroelectronics’ TSC1801 low-side current-measurement amplifier integrates matched resistors to set the gain, which simplifies the circuit design and ensures gain accuracy within 0.15% over the ...

With switching frequencies of MHz and switching edges lasting less than 10 ns, GHz measurement bandwidths are required to visualise some of the important effects occurring in SiC and GaN converters.
