Sorry,I want know which is the output resistor of an opamp with mirror wide swing cascode. The opamp is in this figure
 

It's simply (gm ro^2)n //(gm ro^2)p of the output branch transistors
 

So,Rout=(gm10*rds10 *rds8)//(gm12*rds12*rds14)!
Iwrite well?
And the power total can be Ptot=(K+3)*Itot*Vdd,where Itot is Id1 and Vdd the alimentation!
 

yes I agree with B said
