Zoeppritz's equation is a set of equations that describe the relationship between the displacement amplitude of the reflection and refraction waves and the one of the incident plane wave at the interface of two media, from which the partitioning of wave energy at the interface can be inferred. The echo signal energy is directly affected by the value of the incident angle when oblique incidence of...
Hybrid integration of CMOS and non-volatile memory (NVM) devices has become the technology foundation for emerging non-volatile memory based computing. The primary challenge to validate a hybrid system with both CMOS and non-volatile devices is to develop a SPICE-like simulator that can simulate the dynamic behavior of hybrid system accurately and efficiently. Since spin-transfer-toque magnetic-tunneling-junction...
In this paper, we propose a new envelope-following parallel transient analysis method for the general switching power converters. The new method first exploits the parallelisim in the envelope-following method and parallelize the Newton update solving part, which is the most computational expensive, in GPU platforms to boost the simulation performance. To further speed up the iterative GMRES solving...
Surface quality is one of the most important properties of an industrial product. The conventional techniques obtain the root mean square deviation a, which represents the surface amplitude information. But it is not enough to precisely evaluate the surface quality. Peak number per inch PPI and correlation length T are introduced to identify surface frequency information. According to the theory of...
Stochastic device noise has become a significant challenge for high-precision analog/RF circuits, and it is particularly difficult to correctly include both white noise and flicker noise in the traditional transient verification with an efficient numerical solution. In this paper, a Non-Monte-Carlo transient noise analysis is developed. Both white noise and flicker noise are considered in Itô integral...
It is unclear how to include the newly discovered memristor together with traditional electronic devices into a circuit simulator such as SPICE. To perform a fast prototyping of circuits composed of memristors at nano-scale, this paper introduces a new modified nodal analysis (MNA) to include this fourth circuit element into a first-order differential-algebra-equation (DAE). In the new MNA, magnetic...
With technology scaling down to 90nm and below, many yield-driven design and optimization methodologies have been proposed to cope with the prominent process variation and to increase the yield. A critical issue that affects the efficiency of those methods is to estimate the yield when given design parameters under variations. Existing methods either use Monte Carlo method in performance domain where...
