Predicting the Phase Noise of PLL-Based Frequency Synthesizers
نویسنده
چکیده
Version 4e, August 2006 A methodology is presented for predicting the phase noise of a PLL-based frequency synthesizer using simulation that is both accurate and efficient. The methodology begins by characterizing the phase noise behavior of the blocks that make up the PLL using transistor-level RF noise simulation. For each block, the phase noise is extracted and applied to a phase-domain model for the entire PLL.
