Foil current sense resistors and their applications
Yuval Hernik, Tony Troianello · IEEE Instrumentation & Measurement Magazine · 2012
Many instrumentation circuits depend upon current sense resistors for precision measurements and system controls. This article describes a few such systems, from relatively low power to very high power, and relates aspects of the sense resistor to circuit and system success. The physics of foil resistor technology are reviewed to show how these devices deliver key characteristics required for reliable performance.
