Abstract :
We present in this paper a new design method for increasing the multiplication factor of the Miller capacitance, using active components. This is achieved by connecting the output of the Miller capacitor on a high impedance node and then buffering it to the output of the first gain stage. One can then achieve a very large Miller capacitance multiplication factor, making it possible to efficiently use the Miller effect. This technique has been used to realize a low drop-out regulator which remains stable for very high capacitive loads due exactly to this active Miller multiplication technique.
