Hybrid Pi or T-model for BJT?

  1. Mar 18, 2012 #1
    I was just wondering about when I'm doing small singla analysis with Bipolar Junction Transistor (BJT) is there a basic rule on which model to use, the Hybrid Pi or the T-model?

    I personally always use hybrid ∏, never even use the T model. Here is an article on basics of BJT:


    As the article said at the end, hybird ∏ is much more common. The only time I have seen T model is for common base configuration, I am not even 100% sure at that.
