How to Design Current Measurements in Sensors and Power Electronics
Electrical Engineers
PCB Design EngineersCurrent monitoring is used in sensor interfaces and power electronics; the measurement requirements are very different but the methods are quite similar. This feature involves both analog circuits (dividers, shunts, comparators, amplifiers) and digital processing. The design hinges on required accuracy, space, and signal type (slow sensor voltage, fast power rail transient, or switching current), which determine the measurement front-end and...
