Accurate Phase Noise Prediction in PLL Synthesizers
Op-amp in loop filter While the cases using the passive loop filter (no op-amp) are simply a matter of circuit analysis, the case using the active filter requires some explanation. This case will only be described here; the accompanying analysis can be found in the supporting MathCad documents. With the op-amp in the loop, and the filter configuration shown in Figure 1, four different noise sou...
متن کاملA-New-Closed-form-Mathematical-Approach-to-Achieve Minimum Phase Noise in Frequency Synthesizers
The aim of this paper is to minimize output phase noise for the pure signal synthesis in the frequency synthesizers. For this purpose, first, an exact mathematical model of phase locked loop (PLL) based frequency synthesizer is described and analyzed. Then, an exact closed-form formula in terms of synthesizer bandwidth and total output phase noise is extracted. Based on this formula, the phase ...
متن کاملTechniques for In-Band Phase Noise Reduction in Synthesizers
This paper reviews several techniques used to reduce the in-band phase noise contribution of fractional-N frequency synthesizers. The paper develops several practical techniques for specifying the noise and linearity of components used in a fractional-N synthesizer. As an example, it presents a synthesizer with an in-band phase noise floor of 97 dBc/Hz@10 KHz for an RF output frequency of 2.432...
متن کاملPredicting the Phase Noise of PLL-Based Frequency Synthesizers
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 mode...
