Common Emitter Simulation ?

[Mesho]

I have a problem when I simulate the common emitter on orcad 10

when I put the Ac-source , and check the o/p @ the collector

I found no gain but attenuation

And If I remove it the dc bias become normal

any help please?

AC source is an AC short which of course won't give you any gain.

Hi Mesho

Its simple man AC source is used in ORCAD 10 for AC sweep , and its results in transient wont be accurate , for transient analysis you use VSIN source

it is very simple...use Vsin instead VAc
