In the figure a, it is connected to frequency compensation circuit, and its amplification factor V '= 1, and it uses the full negative feedback. Small signal 3dB bandwidth frequency is 130MHz ( related to the load impedance ). If the load capacitance is large, it must be connected to resistor RD at the input end in series. Figure b shows the frequency characteristic curve of the voltage follower.
