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 ...

Current sensing devices are often desired in the power supply lines of various circuits, such as battery-powered computers, battery chargers or critical circuits requiring thermal forecasting. Figure ...

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 ...

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 ...

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 ...

Here at Hackaday we really like to feature projects that push the limits of what’s possible, or ones that feature some new and exciting technology that nobody has ever seen before. So what’s so ...
