Single miller capacitor frequency compensation techniques: Theoretical comparison and critical review [PDF]
International Journal of Circuit Theory and Applications, 2022 AbstractThis paper presents a systematic analytical comparison of the single‐Miller capacitor frequency compensation techniques suitable for three‐stage complementary metal–oxide–semiconductor (CMOS) operational transconductance amplifiers (OTAs). The comparison is carried out with the aid of a figure of merit that expresses a trade‐off among gain ...

A Technique to Reduce the Capacitor Size in Two Stage Miller Compensated Opamp
2018 9th International Conference on Computing, Communication and Networking Technologies (ICCCNT), 2018 In this paper two stage Miller compensated opamp has been discussed qualitatively and quantitatively. A modification to the conventional compensation network has been proposed, which will reduce the capacitor size hence circuit area. Transfer function for the newly proposed solution has been derived and explained the results.

A high gain, wide-band, fast settling amplifier with no-miller capacitor compensation
IEICE Electronics Express, 2011 A high DC gain, wide band and fast settling fully differential amplifier is presented. The pole zero cancellation technique is used in order to increase the band width of the OTA. Also, a new technique for pole zero cancellation in three-stage OTAs is presented. The proposed OTA simulated in standard TSMC 0.18µm CMOS technology with a 1.8V power supply.

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.

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 ...
