Current-induced spin-transfer torque (STT) is a mainstream method of switching the magnetization of free layer of magnetic tunnel junctions (MTJs) [1-2]. However, currently STT-MTJ is suffering from speed and energy bottlenecks caused by two tradeoffs: firstly, since the critical write current (Ic0) is proportional to the thermal stability barrier (Δ), it is difficult to reduce Ic0 without decreasing...
Recent progress lead spin-transfer torque magnetic tunnel junctions (STT-MTJs) to emerge as a breakthrough for embedded and standalone non-volatile memory [1]. A peculiarity of this technology, however, is its stochastic switching nature [2]. In memory applications, the randomness of the delay to program from a memory state to another requires designing programming times with high safety margins,...
In this paper, a passivity-based control (PBC) algorithm with disturbance reject is proposed to obtain precise position control of a Linear Switched Reluctance Motor (LSRM) driving system in short distance applications. In the framework of the two-time-scale analysis, the whole system is decomposed into two reduced-order models. With the models, an improved PBC algorithm is designed to reject the...
In this paper, the stability of a parallel higher order basis based integral equation solver (HOBBIES) is analysed. The monostatic RCS from a model of 80 wavelength height and 60 wavelength width is simulated at 21 frequencies. The benchmark obtained indicates that HOBBIES takes almost the same amount of time for matrix filling and matrix equation solving for each frequency. The project is executed...
Emerging synapse-like nanoscale devices such as memristive devices and synaptic transistors are of great interest to inspire new circuits or systems and promise adaptability, high density and robustness. We reported recently the Nanoparticle-Organic Memory FET transistor (NOMFET), which exhibits interesting behaviors similar to a biological spiking synapse in neural network. A functional model of...
This paper present a novel algorithm for transient eddy current problems, which is a coupled algorithm of meshless approach in spatial domain and time-parallel algorithm. An example for analyzing transient eddy current of a square metal column is solved by the proposed algorithm to demonstrate the accuracy and efficiency.
