6. Vertical III-V/High-k Nanowire MOS Capacitors and Transistors
Sammanfattning : The emerging nanowire technology in recent years has attracted an increasing interest for high-speed, low-power electronics due to the possibility of a gate-all-around (GAA) geometry enabling aggressive gate length scaling, together with the ease in incorporating high-mobility narrow band gap III-V semiconductors such as InAs on Si substrates. These benefits make vertical nanowire transistors an attractive alternative to the planar devices. LÄS MER
7. Signal readout and sampling in CMOS
Sammanfattning : Advances in CMOS technology have resulted in high-performance and low-cost consumer electronics. One of the main driving forces in this progress is technology scaling. The development of integrated circuits is continuously moving to a system-on-chip realization. LÄS MER
8. Micromachined Three-Axis Accelerometers and Sensor Readout Electronics
Sammanfattning : Miniaturized, MEMS-based, inertial navigation systems are used to track the position of moving objects without an external reference system. Several existing and future applications such as indoor navigation, stability control of vehicles, active prostheses or training aids for sportsmen would benefit from the small size and the low cost of micromachined inertial sensors.

9. A method for including the responses of lumped devices into multi-conductor transmission line model for electrified railways
Sammanfattning : The electrified railway system consisting of overhead lines for traction power supply, auxiliary power, return conductors for traction current and the tracks can be modeled as a system of multiconductor transmission lines (MTL) above a finitely conducting ground. There are several lumped devices connected in series or in parallel along this MTL and the response of the MTL to electromagnetic transients need to be solved along with the device response. LÄS MER
10. Multi-conductor transmission line model for electrified railways: A method for including responses of lumped devices
Sammanfattning : For studying the response to transients caused by lightning and other electromagnetic disturbance sources, electrified railway systems can be represented as a system of multiconductor transmission lines (MTL) above a finitely conducting ground. The conductors present in this system would be wires for traction power supply, auxiliary power, return conductors for traction current, the tracks, and finitely conducting ground. LÄS MER
