 Title: Conductor linear model Post by ranjang on Sep 11th, 2014, 8:10pm I am new to V-AMS .In the V-AMS LRm section  5.6.3 Resistor and conductorWe have following code for Conductance linear model.module my_conductor(p,n); inout p, n;electrical p,n;parameter real G=1; branch (p,n) cond;analog beginI(cond) <+ G * V(cond);endendmoduleWhy we call this as a model for linear conductance .As we have G as always fixed or as paramter.It looks like a current source model.Also In place of analog begin--endIf I replace it with analog block how does it make difference.Thanks,

Perhaps because the current is proportional to the voltage?

 Title: Re: Conductor linear model Post by Geoffrey_Coram on Mar 27th, 2015, 5:08am A current source would have I(branch) <+ iout; but as boe noted, this model's current is proportional to the voltage.analog begin...endis an analog block, so your second question doesn't make any sense.
