load line at ads

i make a design , of nonlinear transistor, igot the i-v curve. how can i plot the load line on this graph ?

Use "Amplifier design Guide" in Design Guide menu. There are many tools in it.

fisrt do DC curave tracing. to plot Id and Vd curve and save the data into say dcTracingDataset.Then use that transistor in HB simulation with a proper bias (u will see the bias point when u plot the load line) put a current probe and a node voltage in this curcuit (for Id and Vd) then plot Id and Vd over the old Id and Vd from dcTracingDataset.

yes, u can use the wizard options of ADS or refered the ADS manual
there are many guides in it !

There's an example in RFboard that shows characterisation for PA, it comes with the relevent loadline curves...

hallo

to my knowledge there r 2 kinds of loadlines dc load line and dynamic load line
for the dc load line go to amplifier design guid and use the very first schematic i think it is called DC , GM and power (some thing like this)
