Antriebsprinzipien für aktive mikromechanische Bauelemente auf der Basis polykristalliner Diamantfilme
Dissertation
In dieser Arbeit werden Antriebsprinzipien für mikromechanische Bauelemente auf der Basis von polykristallinem Diamant untersucht. Diamant ist mit seinen mechanischen, thermischen und elektrischen Eigenschaften ein ideales ...
Mikrofluidik auf der Basis von CVD-Diamant
Dissertation
Das zentrale Thema der vorliegenden Arbeit ist der Einsatz von polykristallinem Diamant als neuartiger Werkstoff in der Mikrofluidik.
Ein besonderes Augenmerk wurde hierbei auf die Entwicklung einer Diamanttechnologie ...
Channel estimation and signal-space diversity for vector-valued transmissions
Dissertation
To combat the degradation effects of the communication channel, which increase the probability of error at the receiver, researchers have turned to the spatial dimension. As a matter of fact, the spatial dimension has a ...
InGaAs metal-semiconductor-metal photodetectors for long wavelength optical communications
Wissenschaftlicher Artikel
Interdigitated metal-semiconductor-metal (MSM) Schottky barrier photodetectors based on the InCaAs-InP material system have been the subject of keen research over the past couple of years for use in long wavelength ...
Correct configuration of process variants in Provop
Arbeitspapier
When engineering process-aware information systems (PAISs) one of the fundamental challenges is to cope with the variability of business processes. While some progress has been achieved regarding the configuration of process ...
Multiple time constant modeling of dispersion dynamics in hetero field-effect transistors
Wissenschaftlicher Artikel
A new approach to the modeling of frequency dispersion effects encountered in the drain current characteristics of state-of-the-art hetero field-effect transistors is presented. The empirical, equivalent-circuit based model ...
Monolithic integration of a folded dipole antenna with a 24-GHz receiver in SiGe HBT technology
Wissenschaftlicher Artikel
The integration of an on-chip folded dipole antenna with a monolithic 24-GHz receiver manufactured in a 0.8-µm SiGe HBT process is presented. A high-resistivity silicon substrate (1000 cm) is used for the implemented circuit ...
A unified approach to charge-conservative capacitance modelling in HEMTs
Wissenschaftlicher Artikel
The voltage dependence of high electron mobility transistor (HEMT) gate-source- and gate-drain-capacitance is described by a set of equations based on a unified charge-conservative model approach. The model is applied to ...
Eine formale Semantik für die Verknüpfung von Verhaltensbeschreibungen in der UML 2
Dissertation
Software development should proceed continuously from requirements through specification to implementation, using an integrated formalism, method and tool set. A state-of-the-art proposal aiming at such an integrated ...
Iterative estimation and detection for single carrier block transmission
Dissertation
This thesis deals with efficient receiver design for digital point-to-point communications. A single carrier block transmission scheme, including channel coding, shall serve as a basis. At the receiver neither knowledge ...
