Dampening oscillation

  1. Dec 3, 2009 #1
    Okay, i've re-tooled my question.

    What role do R2 and C1 play in dampening a sine wave on the current supply IG1 in the following circuit?

    I want to understand the fundamental theory behind this.

    What are your thoughts so far?

    cuz its a simple RC circuit. thats why. the changing current that the cap pulls induces a "compensating" voltage drop in R2.
