Active capacitor multiplier in Miller-compensated circuits
A technique is presented whereby the compensating capacitor of an internally compensated linear regulator, Miller-compensated two-stage amplifier, is effectively multiplied. Increasing the capacitance with a current-mode multiplier allows the circuit to occupy less silicon area and to more effectively drive capacitive loads. Reducing …

Fixed capacitors means that you may have to pick certain discrete values so you can decide to leave the load as somewhat inductive (undercompensated) or capacitive (overcompensated). If the load inductance varies during operation then again you may have to pick some intermediate value and the cancellation may be fairly imperfect.
