Capacitor-free low dropout regulators using nested Miller compensation with active resistor and 1-bit programmable capacitor array [PDF]
IET Circuits, Devices & Systems, 2008 A capacitor-free CMOS low dropout regulator (LDR) using the nested Miller compensation with an active resistor (NMCAR) is presented. It can efficiently control the damping factor and reduce the required Miller compensation capacitance. It can also resolve the trade-off between dc loop gain and damping factor, which existed in the LDR using the nested ...

Nested Miller compensation capacitor sizing rules for fast-settling amplifier design
Electronics Letters, 2005 The conventional capacitor sizing criterion in nested Miller compensation is aimed at giving a third-order Butterworth response to the amplifier in unity-feedback configuration. However, this approach might not represent the best choice for fast-settling and precise amplifier designs.
