Hi folks,

there's a verilog-a description of a single ended charge pump in the library ahdlLib in cadence.
can you help me to model in verilog-a a differential charge pump connected to a filter and to 2 current source (see circuit below), one between (+phase & -phase), the second one connected between (+frequency & -frequency).

           R                                     C                       R
-----~~~~~~~-----------------------||--------------------~~~~~~~~------------
+phase                 +frequency               -frequency                           -phase

thank you very much
