In this work, through-silicon vias (TSV) filled with carbon nanotube (CNT) bundle are investigated based on the equivalent circuit model. The concept of effective complex conductivity is employed for accurately characterizing the impacts of CNT kinetic inductance. The high frequency electrical performance of CNT based TSVs is captured and analyzed. Finally, the TSVs filled with a composite of Cu and...
In this paper, the equivalent circuit model of a pair of TSVs in a passive interposer base is developed, with the nonlinear MOS capacitance effect treated appropriately. Based on the circuit model, the transient analysis of the interposer TSVs is carried out. The results would be helpful for the design and practical applications of interposer-based 2.5-D IC systems.
In this paper, on-chip interconnects based on Cu-single-walled carbon nanotube (SWCNT) composite are studied using transmission line model. The transfer function is obtained and approximated by a linear parameter expression. The relative stability analysis of Cu-SWCNT composite interconnects is carried out by the Nyquist criteria.
The increasing growth of doubly-fed induction generators (DFIG) in wind farms requires attention to understanding its short-circuit behaviour in order to meet grid code requirements. The DFIG model has been well known for years, but many application uncertainties still persist and their impact on short-circuit calculation has to be fully understood. This paper attempts to clarify the influence of...
Harmonics have become an important concern in today's power system network. Conventional Inductive Voltage Transformers (IVT) are used as the essential instrument for harmonic measurement. However, the frequency bandwidths of the IVTs are limited. As a result, they are not suitable for high order harmonic measurement. This paper thus presents the testing and modelling of the frequency response of...
This paper presents details of the behavior of doubly-fed induction generators that are operating at different operation points following system disturbances. Detailed models for doubly-fed induction machine are well known but study based on each individual unit in a wind farm during power system disturbances like fault is not that well reported. When the wind generators are spread over the wind farm,...
