hello guys ,

I am new here. I am working on a fractional PLL in simulink . This is for my thesis . I am working on Analog PLL . I have few problems with the charge pump circuit while simulating in simulink. I need to use a pwrgui for continuous simulation . I am working in modules . the problem I have is once I simulate using the ideal switches , Coudn't genrate any output across the cap. can you please help me with this

thank you and have a great day
