3. System Level Modeling and Verification of All-digital Phase-locked Loop
University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)Abstract : In wirelesscommunication systems, a local oscillator (LO) aims at demodulating radio-frequency signals into baseband signals. The performance of these signals determines the quality of communications which is highly affected by the phase accuracy of local oscillators. READ MORE

5. Design and Simulation of Miscellaneous Blocks of an All-Digital PLL for the 60 GHz Band
University essay from Elektroniksystem; Tekniska högskolanAbstract : A phase-locked loop commonly known as PLL is widely used in communication systems. A PLL is used in radio, telecommunications, modulation and demodulation. It can be used for clock generation, clock recovery from data signals, clock distribution and as a frequency synthesizer. Most electronic circuits encounter the problem of the clock skew. READ MORE
