Hello friends,
I have a pll that was designed and I want to find it's transfer
function, for closed/open loop.
What are the methods that I can use in order to model it in spice(transistor level)
I don't want a behavioral model/verilogA but an electrical model for
continuous time - I want to use the charge pump from the design and to
model all the loop using extra voltages/current sources( in order to model the
pfd/vco)
Thanks
