- A New Four Bit Magnetic Domain Wall Based Multiturn Counter
A New Four Bit Magnetic Domain Wall Based Multiturn Counter
in: IEEE Transactions on Magnetics (2009)
A multiturn counter is proposed which is based on domain wall movement. This sensor has a true-power-on functionality and works gear-less. Due to the new design of the multiturn, the drawbacks of the former design, namely the limitation to 12 turns in maximum and a large die size, are overcome, allowing counting of up to 64 turns at reasonable die size. Parameters as the maximum frequency of the rotating field to be detected and the magnetic working window fit the demands in industrial application.
