Abstract
Systems, structures, circuits, packages and methods provide low-power devices such as sensors and sensor packages having one or more Wiegand coils that can be used for activation of a sensor or other device, as well as potentially supplying operating power. In some embodiments, one or more Wiegand coils can be located in a sensor package, e.g., as one or more discrete components in the package and/or on formed on or connected to a semiconductor die within the package, for providing wake-up and/or continuous power. The Wiegand coil(s) can be separated from the sensor die in some embodiments. In some embodiments, the Wiegand coil(s) can be constructed on the die itself.
