Thanks kripacharya for replyuse this circuit config. It fits better in your circuit

How is it possible to realize this two-port circuit?
Hellowhich 2-port circuit are you referring to ? please post it.
Io is the current between R1 and R2 (it is clear) , V1 is equal to V2, but what is your problem?unable to understand your diagram. What is current Io ? Why would V1 <> V2 ? Looks like a 1-port to me.
sorry.. i cannot help
yes as shown in the schematicso is R1 shorted to R2 at that point ?
hello , thanks for replyI must admit it is confusing. With so many things shorted out there is not much left. The input voltage = the output voltage so it hasn't two ports. The current sources are shorted so can be replaced by a single one. The resistors are shorted so can be replaced by one. You are left with two pins, a current source and a resistor.
I think the wider problem needs to be explained - the question as it stands seems meaningless.

The circuit uses at least circuit elements that need explanation. To represent it in common network syntax, the current sense elements have to be replaced by (possibly very small) resistors. The operation already clarifies that the circuit is actually a two-port.I think the wider problem needs to be explained - the question as it stands seems meaningless.
It is an example for two-port chapter of circuit teory, now I want to make CCCS with mosfet and replace CCCS, and now it is my problem that how can I do this?Most likely it's a homework problem with a certain context (preceeding problems, lecture script, text book etc.). Without knowing the context, it's difficult to guess the intended solution method.
OK, I would be glad you help me to make this circuits with circuit elements, how I replace the CCCS with OTA?I don't see how simple current mirrors can be used instead of a (more or less ideal) CCCS. I would try with a combination of fully differential OTAs.
