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.
