N2 - This brief presents a novel 2.7-V frequency synthesizer for frequency hopping spread spectrum applications. To accomplish fast switching, the frequency synthesizer utilizes a memory access technique to retrieve the precalibrated and digitized tuning voltage values. The phase noise and the frequency accuracy of the frequency synthesizer are analyzed. The channel efficiency, the frequency switching performance, and the output spectral purity are investigated at 2.4 GHz. Measurement shows that the channel switching time is 5 μs. Thus, the proposed synthesizer is promising for frequency hopping wireless communication. The developed architecture is ready to be used for application-specified integrated circuit design. © 2006 IEEE.
