    Hi, this is part of an application note entitled "Low-Noise Amplifier Stability Concept to Practical Considerations" from Maxim.
    Could you help me with the question in the picture? Thanks.

    Can you please give us a little more information.
    Which figure or diagram are you referring to ?
    What is your actual question ?

    Thank you. I thought I figured it out.
    My confusion was from why the left diagram is equal to the right one in Figure 2.4. I was told that node a2 doesn't depend on the input bs and therefore to change from left diagram to the right one all I need is to calculate b2 as a function of bs.
