    the open loop amplifier means, there is no feedback the closed loop amplifier means, feedback exist...

    The gain in open loop is much much high, while this is not the case in closed loop. And yes, as emicho said. It is too.

    @Shayaan_Mustafa just to complete your answer: if you use a negative feedback you have a gain lower than open-loop gain, but if you use a positive feedback you have a gain higher than open-loop gain (as in comparators with hysteresis)

    This is usually in reference to amplifiers. Open loop gain is the intrinsic gain of the amplifier without feedback. Closed loop gain is the overall actual gain with feedback. Both the open-loop gain and the feedback network need to be considered when designing for a target (closed-loop) gain. Source(s): http://en.wikipedia.org/wiki/Operational
