hi,
I do some research in delta-sigma modulator,I m using verilog-A and cadence.I want to model the nonidealities of a differential opamp that I am using in my circuit,I don´t know how to model that in verilog-A !using the macromodel of diff-opamp(like the the input/output resistance of the opamp.
is their any good coding which help me to analyse the non-idealities of the opamp?
thanks

thanks
I ll try it
