Formal research on Ultra-wideband (UWB) technology started in the U.S. in 2002; where its definition was formulated and the frequency allocation in that country established. However, the first ultra-wideband transmission was done during the confirmation of ...
This dissertation considers mechatronic systems driven by piezoelectric ultrasonic motors (PUM). The focus is set on optimal system design and sensorless position control. Mechatronic industry faces the challenge to deliver ever more efficient and reliable ...
Among different analog-to-digital converter (ADC) architectures pipelined ADCs are the most suited for medium sampling frequencies (50-300MSPS) and medium resolutions, i.e. 8 to 14 bits. Having the lowest figure-of-merit (FOM) in its bandwidth and resoluti ...
The internal control of a Modular Multilevel Converter (M2C) aims to equalize and stabilize the submodule capacitor voltages independent of the loading conditions. It has been shown that a submodule selection mechanism, included in the modulator, can provi ...

Recent analysis of empirical data from cities showed that a macroscopic fundamental diagram (MFD) of urban traffic provides for different network regions a unimodal, low-scatter relationship between network vehicle density and network space-mean flow. In t ...
Growth rates of the axisymmetric instability of elongated plasmas in TCV are measured, in open loop configuration, for a wide variety of plasma shapes with elongations and triangularities in the ranges 1.3 < kappa < 2.2 and -0.3 < delta < 0.6, respectively ...
The reasons for the cellular specificity and slow progression of motoneuron diseases such as ALS are still poorly understood. We previously described a motoneuron-specific cell death pathway downstream of the Fas death receptor, in which synthesis of nitri ...
Design and optimization of a simple but efficient operational amplifier (OA) for switched-capacitor finite impulse response (SC FIR) filters are presented. The main design criteria are: proper characteristics for application in SC FIR filters, simplicity o ...
Typical Low Dropout Voltage regulators (LDO), uses an error amplifier in a linear closed loop. The main advantage of such linear regulators is the low standby current due to the absence of switching. In addition, a fully integrated linear regulator with no ...
This paper provides a time-domain feedback analysis of several adaptive schemes with emphasis on stability and robustness issues. It is shown that an intrinsic feedback structure, mapping the noise sequence and the initial weight guess to the apriori estim ...
