Buffer compensation?
HI
As it can be seen from the figure, it is a unit gain follower in essence. In addition to that, a small series resistor and a big external capacitance has been added.
What is the purpose of the series resistor and external cap? Some say it may improve phase margin. But how to analysize it? Thanks!
