Transistors are the fundamental elements in Integrated Circuits (IC). The development of transistors significantly improves the circuit performance. Numerous technology innovations have been adopted to maintain the continuous scaling down of transistors. W ...
This work is part of the innovative "Active Generator" (AG) project. AG is a concept that suggests a new arrangement of the turbine-generator line of a high power utility (a few hundred of MW) in order to de-synchronize the rotation speed of the turbine-ge ...
Technology scaling improves the energy, performance, and area of the digital circuits. With further scaling into sub-45nm regime, we are moving toward very low supply (VDD) and threshold voltages (VT), smaller VDD/VT ratio, high leakage current, and large ...
The semiconductor industry, governed by the Moore's law, has achieved the almost unbelievable feat of exponentially increasing performance while lowering the costs for years. The main enabler for this achievement has been the scaling of the CMOS transistor ...
Medium voltage high-power applications are usually realized using high voltage semiconductors (3.3 kV and above) operated in the hard switching mode with low switching frequencies (several hundreds of hertz). However, for high-power dc–dc converters employ ...
Medium-voltage (MV) high-power converters are usually realized using high-voltage semiconductors (3.3kV, 4.5kV or 6.5kV) operated with low-switching frequencies in the range of several hundred Hz and under hard-switching conditions. However, for medium-vol ...
Resistive random access memory (RRAM) based multiplexers and field programmable gate arrays (FPGAs) are provided. The RRAM-based multiplexers and FPGAs include a 4T1R programming structure to program the RRAMs. The programming structure includes two progra ...
High voltage CMOS active devices inherently have a parasitic vertical bipolar transistor. The parasitic PNP structure can be activated during high-power switching operation causing a potential shift of the substrate. In this work a spice-modeling approach ...
Generalized State Space Average Modeling (GSSAM), of switching converters, offers an opportunity to improve fidelity of a model by inclusion of different harmonic components. Yet, the inclusion of each frequency component contributes to an increase in the ...
In view of the Large Hadrons Collider experiments upgrade, where the inner front-end electronics will require higher supply power, a new power distribution scheme has to be designed. This thesis presents a new and more efficient scheme based on step-down D ...
