Abstract We present a magnetic tunnel junction (MTJ) based implementation of the spike time-dependent (STDP) learning for pattern recognition applications. The proposed hybrid scheme utilizes spin–orbit torque (SOT) driven neuromorphic device-circuit co-design to demonstrate Hebbian algorithm. circuit involves device structure, with domain wall motion in free layer, acting as an artificial syna...

Originality and Novel aspects of this paper (for reviewer’s benefit only, this will be removed in the final manuscript) This paper describes the use of magnetic current imaging to isolate a plane-to-plane short in a printed circuit board. The sensor used for the magnetic current imaging is a SQUID. This technique is realtively new, but the real novel application here is the use of the tool for ...

Circuit models for multiphase coupled inductors are summarized, compared, and unified. Multiwinding magnetic structures classified into parallel-coupled series-coupled structures. For used inductors, the relationships between: 1) inductance-matrix models, 2) extended cantilever 3) magnetic-circuit 4) multiwinding transformer 5) gyrator-capacitor 6) inductance-dual examined discussed. These repr...

Faraday's work inspired the development of electrical motors and generators. Until Maxwell pointed out the significance of Ampere's Law, there was no rigorous design method for magnetic devices. His interpretation strongly influenced the creation, by others, of the 'magnetic circuit' approach, which became the seminal design technique. This, utilizing the concept of reluctance, led to the desig...

Brushless permanent magnet surface inset machines are interested in industrial applications due to their high efficiency and power density. Magnet segmentation is a common technique in order to mitigate cogging torque and electromagnetic torque components in these machines. An accurate computation of magnetic vector potential is necessary in order to compute cogging torque, electromagnetic torq...
