i want to know what is rds in dc operation point when we print for folded cascode

 

[dick_freebird]

The meaning, is |(Vds/Id)| and about as close as you
can get to small signal Rout, and that is its usefulness.

If you want someone to tell you what the "rds"
simulation result should be to achieve something
in particular, for a topology and technology, that
wants a little more specificity. And will probably
still remain "an exercise for the student" beyond
basic hints.

I think you are talking about the drain-to-source resistance of a MOSFET.

Metal Oxide Field Effect Transistor: What is RDS(on)?

RDS(on) stands for “drain-source on resistance,” or the total resistance between the drain and source in a Metal Oxide Field Effect Transistor, or MOSFET..

Q: What is the drain-to-source on-resistance R_DS(ON) of a MOSFET? A: This is the resistance between the drain-source when MOSFET is on at the specified gate-voltage.
