Opis

Phase lock loop frequency synthesis finds uses in a myriad of wireless applications - from local oscillators for receivers and transmitters to high performance RF test equipment. As the security and reliability of mobile communication transmissions have gained importance, PLL and frequency synthesisers have become increasingly topical subjects. Phase Lock Loops and Frequency Synthesis examines the various components that make up the phase lock loop design, including oscillators (crystal, voltage controlled), dividers and phase detectors. Interaction amongst the various components are also discussed. Real world problems such as power supply noise, shielding, grounding and isolation are given comprehensive coverage and solved examples with MATHCAD programs are presented throughout.

• Presents a comprehesive study of phase lock loops and frequency synthesis in communication systems
• Written by an internationally-recognised expert in the field
• Details the problem of spurious signals in PLL frequency synthesizers, a topic neglected by available competing titles
• Provides detailed theorectical background coupled with practical examples of state-of-the-art device design
• MATHCAD programs and simulation software to accompany the design exercises and examples

This combination of thorough theoretical treatment and guidance on practical applications will appeal to mobile communication circuit designers and advanced electrical engineering students.

Phase lock loops (PLL) with frequency synthesisers are key components of modern communication systems. Their growing use in controlling numerous wireless applications continues to drive the need for coherent information on their design and simulation. Balancing a detailed background in theory with practical applications of state–of–the–art device design, this book provides expert advice and in–depth discussions on switching phenomena, higher order loops and noise properties of oscillators, dividers and phase detectors. Phase Lock Loops and Frequency Synthesis : describes the basic properties of PLLs, emphasizing natural frequency and damping factors. investigates the theory control system stability. examines spurious signals in PLL frequency synthesizers, particularly signa–delta types. discusses individual blocks encountered in PLL systems. presents practical higher order PLLs and solutions based on the normalized 2nd order forms. Written by an internationally–recognised expert in the field, this book will prove an essential tool for practising telecommunications engineers developing new systems and components, and professional analog and digital circuit designers. Optical communications engineers, graduate electrical engineering students and researchers will find the practical examples useful.
