Abstract :
A theoretical study of the high frequency characteristic of an inverting amplifier based on a current feedback operational amplifier is presented. It is shown that the amplifier bandwidth and step response can be improved using a pole-zero compensation technique. Simulation and experimental results agree with the theory
