ISSCC 2004 / SESSION 10 / CELLULAR SYSTEMS AND BUILDING BLOCKS / 10 . 6 10 . 6 A 10 μ s Fast Switching PLL Synthesizer for a GSM / EDGE Base - Station

چکیده
GSM & EDGE base-stations require synthesizers that can frequency hop over the full 75MHz TX or RX band in < 10us and also have very low phase noise and spurious. To date, these conflicting requirements can only be accomplished using a costly "ping-pong" architecture where one synthesizer is locking to the next desired frequency while the other is active as the LO. The proposed fast switching synthesizer can meet all these requirements with a single PLL.

T his is the final article in a five-part series on microwave frequency synthesizers. It concludes with a review of advanced synthesizer solutions. Although synthesizers can be found in virtually any microwave system, test and measurement (T&M) is probably the most challenging application that calls for advanced synthesizer techniques. This final article addresses some specific T&M requirements...

PLLs are important building blocks that are used to generate and distribute clocks in all high-performance digital systems. Integrating PLLs on large digital chips in deep submicron processes poses three main challenges. First, power supply noise caused by increased digital switching currents degrades the jitter performance of the VCO. Second, the wide loop bandwidth required to suppress ring o...
