    I've found this interesting lecture
    but i don't understand open loop gain with resistor series capacitor
    as load.In fig. 6.15 opamp's open loop gain is represented: it is
    calculated (i think) at node Vout of fig 6.14, so pole is equal to 1/
    (Ro+Riso)*Cl. I don't understand how zero is obtained....
    Can you help me?

    Undestand this any amplifier will oscillate at higher frequency if when you cross the 0 Db point at a slope greater then one. What you read is spice simulation . That is not the real world . Spice can make do anything you want .
