The main goal of this thesis is to investigate the feasibility of a quadrature radio frequency receiver front-end using a second-order sampling topology in CMOS. Second-order sampling combines subsampling with a non-uniform sampling scheme. This non-uniform sampling scheme comprises of two uniform sampling streams with a small time delay between both streams, which allows the generation of an I and Q channel.
In this work, physical phenomena related to the growth and phase formation of alumina, Al2O3, are investigated by experiments and computer calculations. Alumina finds applications in a wide variety of areas, due to many beneficial properties and several existing crystalline phases. For
Radio frequency (RF) lesioning and deep brain stimulation (DBS) are the two prevailing surgical treatments for movement disorders within the field of stereotactic and functional neurosurgery. For RF-lesioning, a small volume of brain tissue is coagulated and knowledge of the lesion size
The characterization and switching system for a hybrid Free-Space Optical (FSO) with Radio Frequency (RF) backup link is described. Such hybrid systems are used to take advantage of the large bit rates achieved with FSO while maintaining high reliability with a RF
