Efficient Simulation Techniques for Modulated Delta-Sigma Fractional-N Synthesizers
In this technical paper, we show an efficient simulation methodology for the analysis of spurs in a fractional-N delta-sigma PLL. Delta-sigma PLLs can be used for frequency synthesis or even direct modulation, typically for GMSK or GFSK. The simulators used are Eldo, Eldo RF and ADMS RF.
