The effects of fast neutron radiation up to flux of 1014 cm−2 (1 MeV equivalent flux) upon the turn-on and forward static characteristics of MOS-Controlled Thyristor (MCT) are described in this work, based on physics-based 1-dimension analytical calculation and 2-dimension Silvaco simulation. It is reported for the first time that dependency of on-state specific resistance (Ron) upon neutron flux...
Ever-increasing complexity in high-speed electronic devices and systems presents significant computational challenges in the numerical analysis in terms of desired accuracy, efficiency, and scalable parallelism. The objective of this paper is to investigate high-resolution, high-performance full-wave field solvers for scalable electromagnetic simulations of product-level integrated circuits (ICs)...
In order to realize load current imbalance measuring for paralleling IGBT devices, the authors propose a novel method for measuring the imbalances from IGBT gate charge. In the study, an analytical model between gate charge and on-state current has been worked out to find the current differences of IGBT among each paralleled sub-circuits. The results from simulation show that the analytical model...
The objective of this work is to investigate high-resolution, high-performance full-wave field solvers towards scalable electromagnetic simulations of product-level ICs and electronics. The emphasis is put on advancing parallel algorithms that are provably scalable, facilitating a design-through-analysis paradigm, and enabling concurrent multi-scale modeling and computation. The capability and benefits...
Crosstalk noise has become a major performance inhibitor in high speed digital system. This is especially the case in package designs, connector assemblies and circuit interconnects designs. With the simultaneous miniaturization of electronic systems and decreasing signal rise time, it is important to be able to predict major sources of crosstalk and to stay within the cross-talk budget for high-speed...
The fourth-order active loop filter is employed to design the PLL frequency synthesizer at S-band in this paper. By using ADIsimPLL3.1 the transfer function and the phase noise are simulated. The testing results of the real circuits performance parameters coincide with the simulated results very well. And it is verified that the high order loop filter can improve the phase-noise of the PLL frequency...
A new sub-space max-monomial modeling scheme for CMOS transistors in sub-micron technologies is proposed to improve the modeling accuracy. Major electrical parameters of CMOS transistors in each sub-space from the design space are modeled with max-monomials. This approach is demonstrated to have a better accuracy for sub-micron technologies than single-space models. Sub-space modeling based geometric...
In the oil-gas pipeline magnetic flux leakage (MFL) detection, the qualitative and quantitative analysis can be achieved. The circumferential excitation technology is an effective way to detect or size axial direction of defects reliably; Magnetic circuit design has become the key part of this technology to meet the magnetized requirements of circumferential excitation. This paper studies the magnetized...
