Frequency synthesizers are an essential building block of RF
communication products. They can be found in traditional consumer
products, in personal communication systems, and in optical
communication equipment. Since frequency synthesizers are used in many
different applications, different performance aspects may need to be
considered in each case. The main body of the text describes a
conceptual framework for analyzing the performance of PLL frequency
synthesizers, and presents optimization procedures for the different
performance aspects. The analysis of the PLL properties is performed
with the use of the open-loop bandwidth and phase margin concepts, to
enable the influence of higher-order poles to be taken into account from
the beginning of the design process. The theoretical system analysis is
complemented by descriptions of innovative system and building block
architectures, by circuit implementations in bipolar and CMOS
technologies, and by measurement results. Architectures for RF
Frequency Synthesizers contains basic information for the beginner as
well as in-depth knowledge for the experienced designer. It is widely
illustrated with practical design examples used in industrial products.
