In nanoscale MOSFETs with narrower width, the random telegraph noise (RTN) is conspicuous during the device aging caused by negative bias temperature instability (NBTI), which leads to difficulty for accurate assessment of end-of-life variability. Based on fast voltage stepping stress (FVSS) technique to predict the long-term degradation, an improved extraction method is proposed for eliminating the...
This paper introduces the application of a switched-diode-capacitor voltage accumulator (SDCVA) on conventional boost converter. This study aims to obtain two different kinds of multi-input step-up converters with high voltage gains, low component stresses, low ripples, simple control, and high conversion efficiencies: one is based on the parallel SDCVA and the other based on the serial SDCVA. The...
In this paper, the theoretical analysis, field testing, ANSYS finite element analysis software was adopted to analyze the process of projectile penetration. Which established the body of missile and concrete target to obtain the acceleration distribution of missile. So as to provide theoretical support of missile structure, damage assessment, verify the feasibility of solving problems in high-speed...
Aiming to the shell protection for the circuit, on the basis of analysising the relationship between the stress on passing the cover of protective shell and the least plastic flection stress, utilizing the principle of the wave front conservation, the equation is built to evaluate the impact resistance on protective shell, and the evaluation factor of the impact resistance can be extracted from this...
We present the Green's function for the scattering of SH waves by an elliptical cavity in an elastic half-space combining with the technique of conformal mapping and multi-polar coordinate system. Then we deduce the dynamic stress concentration factor (DSCF) around the oval cavity based on the Green's function. Numerical results are carried out by changing the position and the shape of the cavity,...
The problems of SH-wave scattering, which is caused by half-space circular cavity near the bimaterial interface and crack of arbitrary length and arbitrary position, are studied in this paper based on the field of elastodynamics, and the methods of Green's Function, complex variables function, the method of crack-division and multi-polar coordinates are used here. Firstly, a suitable Green's function...
