4. Performing Basic Noise Analysis Using thePLLDesign Assistant 使用PllDesign完成PLL噪声的行为级仿真。设置好相噪曲线的刻度范围,Noise axis limits: 1e4 1e8 -170 -60。原文依次使用了2阶的ΣΔ频综(噪声传递函数[1 -2 1])和7-bit PFD/DAC频综,最终的相噪结果如图6所示。 图5 PllDesign参数设置界面 ...
31 1 Setup Download and install the CppSim Version 3 package (i.e., download and run the self-extracting file named setup_cppsim3.exe) located at: http://www.cppsim.com Upon completion of the installation, you will see icons on the Windows desktop corresponding to the PLL Design Assistant...
CppSim/VppSim is free for academic and commercial use, and the install file includes all files necessary to run CppSim/VppSim along with supporting programs such as NGspice and the PLL Design Assistant. However, it is also useful to separately install Python, Octave, or Matlab® in order ...
Clock and Data Recovery (CDR) Design Using The PLL Design Assistant and CppSim Programs Design of a Wideband Fractional-N Frequency Synthesizer Using CppSim CppSim Library: Wideband Fractional-N Synthesizer Example (wbsynth_example.tar.gz)
CppSim automatically generates, compiles, and runs C++ code corresponding to the schematic design that you create. Graphical Interface: Systems are specified and simulated within a schematic editor, Sue2, and results are viewed using a waveform viewer (CppSimView or GTKWave). ...
