The op amp-based current sensing circuit described here is not new, it has been around for some time, but with very little discussion of the circuit itself. Somewhere along the line it was informally ...

Here are the steps required to select the transformer and how to design the circuit needed to meet the end use in a manner that prevents transformer saturation Average current-mode control (CMC) ...

Seeking something-or-other, I came across a high-side current sense circuit that I had never noticed before. Here it is (right), in an app note for the OnSemi NCP3020A buck dc-dc converter controller, ...

Accurately measuring current flow is a standard requirement in several applications (Fig. 1). Depending on the specific need, the options available to designers can include discrete designs assembled ...

The smart grid is the next evolution of the electricity grid with the convergence of electric power, telecommunications infrastructure and information technology. The ultimate goal is to allow ...

Current sensing remains a challenge and while most engineers use DCR current sensing it is notoriously inaccurate. So what can be done to improve accuracy? The buck converter is the most common power ...

Engineers who design circuits for automotive equipment, industrial devices, test-and-measurement instruments, and solar-power inverters often must measure supply currents and in most cases, they pass ...
