1. Integrated Frequency Synthesis for Convergent Wireless Solutions
Sammanfattning : Wireless transceivers combining several standards in one unit are of key importance. In order to reach the ultimate goal of maximizing the performance-to-cost ratio of such modules, a careful study of the target application, the architecture, and the frequency planning is strongly required.

2. On PLL Modeling and Design in Nanometer‐Scale CMOS
Sammanfattning : Integrated circuits play a vital role in our everyday lives, from wireless gadgets and multimedia players to sensors and processors that control vital infrastructure. Since most electronic circuits need a clean, stable clock or carrier to function, one of the most important components of integrated circuits is the phase-locked loop. LÄS MER
3. Design and Calibration of integrated PLL Frequency Synthesizers
Sammanfattning : Thanks to its ability to generate a stable yet programmable output frequency, Phase Locked Loop (PLL) frequency synthesizers are found in most modern radio transceivers. All practical PLL implementations suffer from unwanted frequency components such as phasenoise and spurious tones, and since these components affect system performance they must be predicted and minimized.

4. Digital Phase Locked Loops for Radio Frequency Synthesis
Sammanfattning : The demands for an ever higher data rate and a more varied functionality at minimal cost and power consumption have been the driving force behind most innovations in wireless communication systems. Intensive efforts have been made to develop Radio Frequency (RF) Integrated Circuits (ICs) and systems using low-cost Complementary Metal Oxide Semiconductor (CMOS) processes. LÄS MER
5. Design and Analysis of Charge-Pump Bases Frequency Synthsizers
Sammanfattning : Most telecommunication systems employ modulation techniques that require the transceiver to be capable of accurately estimating the phase of the transmission signal. The frequency synthesizer is a key element and extensively utilized to synthesize frequencies for such radio-frequency communication systems. LÄS MER
