This paper presents a method to model external capacitors behavior face to continuous and transient events. Temperature and the physical dimensions of the capacitors have been considered in order to predict Electromagnetic Compatibility performances of an equipment or a system. The different tests were performed on ceramic capacitor series X7R from Murata. A model has been developed in Verilog-A....
This contribution derives an efficient approach to model a coupled electro-thermal design problem for transient system simulation, using an analogue simulator, like SPICE. It introduces the electrical and thermal modelling procedures and the coupling of both models. The electrical model is based on the fundamental equations of semiconductor physics. Using the respective physical parameters the model...
It is difficult to directly measure the transient conductor temperature of operating cable, however, which plays a significant role in reflecting its operation state and controlling its load. So it is essential to calculate and monitor the transient cable conductor temperature. A model of calculating transient cable conductor temperature based on support vector machine (SVM) is proposed in this dissertation...
This paper presents a study of transient mutual thermal coupling occurring between the fingers of trench isolated SiGe HBTs. Three-dimensional thermal TCAD simulations have been carried out to obtain the temperature evolution in transient operation in a multifinger HBT structure. The same behavior has been simulated using a netlist-based model, which provides an accurate representation of the substrate...
There is a problem peculiar to photovoltaic (PV) generation systems that output power changes with weather conditions. The paper describes a PV generation system with high reliability which can always stably supply clean electric power to loads. The stabilization of the PV generation system is realized here by compensating the generated electric power, which changes with weather, in cooperation with...
The control of cable transmission capacity is decided by the cable capacity, which is determined by the long-term enduring temperature. The cable capacity is usually calculated by the formula of IEC-60287, in which the conductor temperature is supposed to be 90°C (when its insulation is XLPE), and the cable surface reaches its maximal temperature. However, the maximum temperature of the cable surface...
The paper deals with the nonlinear compact thermal model of SiC power semiconductor devices based on the Cauer network.

Timing-error detection and recovery circuits are implemented in a 65 nm resilient circuit test-chip to eliminate the clock frequency guardband from dynamic supply voltage (VCC) and temperature variations as well as to exploit path-activation probabilities for maximizing throughput. Two error-detection sequential (EDS) circuits are introduced to preserve the timing-error detection capability of previous...
A physical yet analytical phase change memory (PCM) model simultaneously accounting for thermal and electrical conductivities is presented. Due to the physics based nature of the model, the essential temperature from heating and cooling of PCM during operation is instantaneously updated. More importantly, the model can be applied to non-conventional circuit design technique. We show that for the first...
A new thermal model based on Fourier series expansion method has been presented for dynamic thermal analysis on power devices. The thermal model based on the Fourier series method has been programmed in MATLAB SIMULINK and integrated with a physics-based electrical model previously reported. The model was verified for accuracy using a two-dimensional Fourier model and a two-dimensional finite difference...
