PLL Design
A Phase-Locked Loop (PLL) is a closed-loop circuit that compares its output phase with the phase of an incoming reference signal and adjusts itself until both are aligned, i.e., the PLL output's phase is "locked" to that of the input reference. Once the loop is locked (the phase ...

PLL Design Assistant:
Part of CPPSim, takes as input a desired transfer function and calculates the open-loop parameters required to achieve the design
CPPSim 3:
CppSim is a free behavioral simulation package that leverages the C language to allow very fast simulation of systems. Users enter designs in a graphical schematic editor, Sue2, run the simulations using a provided GUI tool, and then view the results within CppSimView (a custom waveform viewer for CppSim). Users can also run simulations and plot signals directly within Matlab.
