How to Lay Out Kelvin 4-Wire Current Sense PCB Pads for Accurate Readings
For accurate Kelvin sensing, use two force pads and two sense pads, with the sense taps placed close to the resistor body inside the force…
Current Sense Resistor Inductance and Switching Noise
A current-sense resistor can add switching noise to the signal it is meant to measure. Its parasitic inductance produces an L·di/dt voltage in…
