Can we have an equation of force in case of an amplifier?

Dear all,

I would like to know if an equation of force can be worked out in case of an amplifier? So far i know that in case of an oscillator (duffing oscillator) it is there, but in case of amplifier m not sure.Hence i would like to know if it is posble or not.

Can you expand your question ?
Do you want an nonlinear equation to represent an amplifier ? Or something else..;

yes i want the nonlinear eqn for amplifier.What are the factors that needs to be considered in this case?

Recently, Agilent has developed a nonlinear equation based models that characterize a nonlinear circuit.
The are called as X-Parameters and they are obtained either by measurments or simulation with appropriate models.The X-Parameters are used instead of circuit itself to accelerate the simulation time.
The X-Parameters can be replaced with a nonlinear complex circuit so that nonlinear behaviour of the circuit is represented by these equations.

Sir, thanks for your reply.I hv gone through the link provided by you.It does give some info regarding the same.X-parameter indeed new to me as i never heard of it.But i would like to have the mathematical derivations of the same,which i couldn't get in the given link.If u have it with u, plz provide me the same.
