| Abstract: | The establishment of behavioral-level system simulation platform can provide the accurate and overall time-domain simulations for Fractional-N Frequency Synthesizers design.It laid special stress on analyzing the 2/3 multi-modulus programmable divider and MASH Σ modulator.A new approach for calculating the parameters of loop filter was given.A set of Simulink circuit modes was designed.These modes structure an integrity Σ Fractional-N Frequency Synthesizers which can be used to predict and verify the circuit topologies in practice. |
| Keywords: | Σ-Δ frequency synthesizers 2/3 multi-modulus programmable divider MASH loop filter Simulink |
