A 2.4-GHz CMOS monolithic VCO based on an MOS varactor

A 2.4-GHz CMOS VCO is presented employing pMOS transistors as voltage-controlled capacitances and on-chip hollow spiral inductors. The design was implemented in a standard digital 0.8 μm CMOS process and exhibits a 15% tuning range at 2.5 V supply voltage and 9 mA supply current. Phase-noise measurements show a phase-noise of about -118 dBc/Hz at 1 MHz from the carrier

Validation of the physiological model of sleeping bags defined in EN13537 (2002)

Abstract in UndeterminedIn this study, we validated comfort and limit temperatures of four sleeping bags with different levels of insulation defined according to EN 13537. Six male subjects and four female subjects underwent totally 20 two-hour exposures in four sleeping bags at four intended testing temperatures: 11.2, 3.8, 2.1 and -9.0 °C. The subjective perceptions and physiological responses o

Evaluation of trellis termination strategy for turbo codes in UMTS

This input document proposes a trellis termination startegy for turbo codes in UMTS. The proposal is based upon the fact that the extrinsic information used in the decoding of turbo codes mitigates the effect of a truncated trellis, and that this mitigating effect can be enhanced by imposing certain restrictions on the interleaver design. The simulation parameters used in the comparison bewteen di

Structure and function of microbial communities in constructed wetlands - influence of environmental parameters and pesticides on denitrifying bacteria

This thesis addresses the interactions and relationships between natural aquatic bacterial communities, environmental parameters, anthropogenic chemicals and the denitrification pathway in the habitat of agricultural constructed wetlands. The main aim was to gain fundamental knowledge of the drivers behind the processes of the denitrification (i.e. nitrogen removal) in constructed wetlands, hence,

Consensus analysis via integral quadratic constraints

This note proposes a unified approach to analyse linear time-invariant consensus problems via the use of integral quadratic constraints (IQCs) without recourse to loop transformations, which may cloud the inherent structural properties of the multi-agent networked systems. The main technical hindrance to using IQCs lies in the presence of the marginally stable integral action in consensus setups.
