Sammanfattning : Advances in microelectronics technology have enabled us to integrate a complex electronic system (such as a radio) on a single chip or in a single package module, known as system-on-chip (SoC) and system-on-package (SoP) paradigms. This brings not only new opportunities for system integration, but also challenges in design and implementation. LÄS MER
Sammanfattning : The rapid evolution of wireless communication systems and the developmentof new standards require that wireless transmitters process several types ofstandards across multiple bands. Power amplifiers (PAs) are key componentsin wireless transmitters because they have a big impact on the overall systemperformance in terms of their bandwidth, efficiency, and linearity. LÄS MER
Sammanfattning : One of the main challenges posed by 4G wireless communication systems is achieving flexible, programmable multi-standard radio transceivers with maximum hardware share amongst different standards at a minimum power consumption. Evaluating the feasibility and performance of different multi-standard/multi-band radio solutions at an early stage, i. LÄS MER
Sammanfattning : The World today is deeply transformed by the advancement in wireless technology. The envision of a smart society where interactions between physical and virtual dimensions of life are intertwined and where human interaction is mediated by machines, e.g., smart phones, demands increasingly more data traffic.

Sammanfattning : The development of the transistor and its continuous down-scaling has allowed during the last decades the appearance of cheap wireless communication systems targeting consumer products. The complexity of these systems has increased dramatically during the last years, mainly fueled by both the Moore law and improvements in communication theory. LÄS MER
