Abstract
In this work, a novel phase frequency detector (PFD) architecture using pass transistor logic is proposed. The circuit does not have a reset path, resulting in the elimination of blind zone and dead zone. The -V characteristics of the PFD were found to have better linearity across the range of to due to the absence of blind and dead zones. The Taguchi and ANOVA statistical techniques were used to optimize the PFD. The optimized PFD exhibited a phase noise of −142.24 dBc/Hz, consumed 5.64 W of power and had a maximum operating frequency of 5.25 GHz, and a delay of 10.65 ps. Using this PFD, a GHz-range synthesizer was designed, and its performance characteristics were obtained from circuit simulations using CADENCE Virtuoso. The synthesizer had a power consumption of 4.25 mW at a supply of 1.8 V, achieved a lock time of , and could generate frequencies ranging from 0.1 GHz to 4.75 GHz while occupying a chip area of 0.013 . Moreover, the work introduced a new figure of merit, FoM. The synthesizer has potential applications in various devices such as radio receivers, televisions, mobile phones, satellite receivers, and GPS systems.
期刊介绍:
Integration''s aim is to cover every aspect of the VLSI area, with an emphasis on cross-fertilization between various fields of science, and the design, verification, test and applications of integrated circuits and systems, as well as closely related topics in process and device technologies. Individual issues will feature peer-reviewed tutorials and articles as well as reviews of recent publications. The intended coverage of the journal can be assessed by examining the following (non-exclusive) list of topics:
Specification methods and languages; Analog/Digital Integrated Circuits and Systems; VLSI architectures; Algorithms, methods and tools for modeling, simulation, synthesis and verification of integrated circuits and systems of any complexity; Embedded systems; High-level synthesis for VLSI systems; Logic synthesis and finite automata; Testing, design-for-test and test generation algorithms; Physical design; Formal verification; Algorithms implemented in VLSI systems; Systems engineering; Heterogeneous systems.
