Best ResponseYou've already chosen the best response.0CC config has output voltage same as input voltage (Vo/Vi = 1) high input impedance and low output impedance .therefore it can be used for impedance matching purposes(matching high impedance source with low impedance load) .Its also used for isolation purposes.. to avoid magnetic coupling between two stages
