verilog a slew rate

Dear all,

I want to know the effect of dc-gain, ugbw and slew rate in 2-1 MASH sigma-delta modulator. How to model fully differential opamp by using Verilog-A?
 

verilog a slew

1,there is an example of differential opamp wirtted in verilogA in the bmslib. You can add the parameter includes gain, gbw and slew rate.
path:/edatools/cadence/ic5141/ic5141_200903/tools.sun4v/dfII/samples/artist/bmslib;
2,you can construct your differential opamp by model writer.
 

You can use cadence modelwriter to create it.
If u want a more indepth view read this book

Analog behaviour modeling in Verilog A by Ira miller and Dan FitzPatrick. you can download it from the internet.
