when i simulate a bipolar ciruit , i must to give the value of emitter area , but i do not know the unit . is it µm? who can help me? thank you very much
Re: how to give the value of device area of transistor in ca
Hi,
That much I know is that along with the device models there is a paramater called multiplier. By default it is 1. And by default it gives the maximum current etc. according to its model. You can change the multiplier to 1.2 etc; which a numeric value just will be multiplied to the default emitter area.
And in general the are are in sq. um. But be confirmed it. You can check the values etc. when you run the icfb and messages coming in the icfb command window.

thank you for your answer
then you mean the default area can be calculated using the current gived in the device model?

Not exatly. By the multiplier you change the emitter area. But the total device size doesnot mean emitter area only. WHy don't u do one thing; you go for laying out the thing and measure it there by the ruler (for cadence excel, "k")....
