fundamental questions about periodic steady state and pss analysis
Jul 14^th, 2009, 7:13pm

hi there,
what is the difference between the steady state of a circuit (in the context of analog design) and the periodic steady state of a circuit (in the context of RF design)? And the difference between pss analysis and DC analysis(or maybe AC , tran?).I am really confused about these concepts, please help!

As I understand:
In pss analysis we get a variable with fundamental frequency operating point .
In dc (op) analysis we get constant operating point, which is used to calculate small-signal parameters.
In tran analysis OP calculate at every time step.

So pss plays OP analysis role for all small-signal periodic analyses.
