چکیده

This paper presents a new strategy to simulate fractional frequency synthesizer behavioral models with better performance and reduced simulation time. The models are described in Verilog-A with accurate phase noise predictions and they are based on a time jitter to power spectral density transformation of the principal noise sources in a synthesizer. The results of a fractional frequency synthesizer simulation is compared with state of the art Verilog-A descriptions showing a reduction of nearly 20 times. In addition, experimental results of a fractional frequency synthesizer are compared to the simulation results to validate the proposed model.

Modeling and Simulation to the Design of Σ∆ Fractional-N Frequency Synthesizer

A set of behavioral voltage-domain verilogA/verilog models allowing a systematic design of the Σ∆ fractional-N frequency synthesizer is discussed in the paper. The approach allows the designer to accurately predict the dynamic or stable characteristic of the closed loop by including nonlinear effects of building blocks in the models. The proposed models are implemented in a three-order Σ∆ fract...
