When tasked with a current sensing requirement, designers typically look first to using dedicated resistors designed for this task. Occasionally though there is the temptation to consider sensing ...

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 ...

In-circuit testers rely on bed-of-nails-type fixtures that give the tester access to every node (or net) of the printed circuit board (PCB). Using this access, the tester takes a divide-and-conquer ...

A voltage-to-frequency converter (VFC) can easily measure current flow and convert it to a digital signal understood by the timer/counter input of a microcomputer (µC) or microprocessor. It's a ...

In various industries and applications, it’s crucial to monitor the current and frequency of devices in real-time. These ...

We were recently tipped off to quite a resource — on the Texas Instruments website, there’s a page where you can view and download a compendium of analog sub-circuits. Individual circuits can be ...
