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 ...

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 ...

Abstract: To solve the problem that the load current sensing precision of transistor power switch chip was easily affected by the offset voltage of operational amplifier(op-amp), current sensing mode, ...

Abstract: A new on-chip current sensing circuit for the over-current protection of the electronic ballast is presented in this paper. The proposed scheme increases the sense accuracy and noise ...

Trying to get a circuit to sense its own current consumption can be a little tricky. That said, there are plenty of specialist three and four terminal chips that will sense across a resistor in the ...

Resistor-based current sensing is simple, easy to use, low cost, extremely linear and requires no calibration. The statement that voltage across a resistor is directly proportional to the current ...

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 ...

What qualities are needed for current sensors in an automotive environment? Warren Pettigrew spells out the requirements. Today what is expected of automotive sensors is quite different to what was ...
