Question

What is the maximum load capacitance CL that can be connected to the output of the voltage follower as shown if the phase margin of the amplifier is to be 60◦? Assume that the amplifier voltage gain is described by this transfer function, and that it has an output resistance of Ro =500 Ω: 

A(s) =107 /(s+50)
