As explained before, two-stage operational amplifier exhibits two poles below the unity open-loop gain. As shown on figure 3, when the gain of the two-stage operational amplifier is equal to the unity gain frequency, the phase shift is less than 45 degrees. Therefore, to achieve stability, a two-stage operational amplifier must be compensated.
