Distortion analysis of Miller-compensated three-stage amplifiers
IEEE Transactions on Circuits and Systems I: Regular Papers, 2006This paper proposes a theoretical approach for evaluating distortion in the frequency domain of three-stage amplifiers adopting two commonly used compensation techniques, namely the nested Miller (NM) and the reversed NM. The analysis is based on appropriate amplifier modeling and on the assumption that the nonlinearity generated by each stage is ...

A Simple Miller Compensation With Essential Bandwidth Improvement
IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2017A novel technique for adaptive frequency compensation in negative feedback amplifiers is proposed. It is demonstrated that a simple reconnection of the compensation capacitor in a two-stage Miller op-amp leads to a pseudoconstant bandwidth for a moderate range of closed-loop gains, without requiring additional power dissipation or extra silicon area ...

2013 International Symposium onVLSI Design, Automation, and Test (VLSI-DAT), 2013
A novel current-mirror miller compensated two-stage amplifier is presented. The proposed design improves both large-signal performance and small-signal performance of conventional two-stage amplifiers. This design eliminates the low-frequency right half-plane zero and reduces the output parasitic capacitance of the first stage without inducing ...

Low-dropout regulator design using reverse nested miller compensation
2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC), 2015A multi-stage low-dropout (LDO) linear regulator with reverse nested miller compensation is presented. The multi-stage structure can derive the high dc voltage gain to insure the load/line regulation. The error amplifier adopts cascading technique using reverse nested miller compensation with current buffer for the low supply voltage stable frequency ...

1-GHz operational amplifier with multipath nested Miller compensation
Proceedings of IEEE International Symposium on Circuits and Systems - ISCAS '94, 2002A monolithic operational amplifier has been realised, which has a unity-gain frequency of 1 GHz. The amplifier is fully compensated for unity-gain feedback, having a phase margin of 60/spl deg/ at 1 GHz. This high bandwidth is the result of an all-NPN signal path. A three-stage configuration reaches a DC-gain of 74 dB in a 50 /spl Omega/ load, while an

Analytical comparison of reversed nested Miller frequency compensation techniques
International Journal of Circuit Theory and Applications, 2009AbstractIn this paper, novel and previously proposed reversed nested Miller compensation (RNMC) networks are analyzed and compared, and their design equations are also presented. Hence, this paper is the natural extension of a previous paper by the authors (Int. J. Circ. Theor. Appl.

Design Procedures for Three-Stage CMOS OTAs With Nested-Miller Compensation
IEEE Transactions on Circuits and Systems I: Regular Papers, 2007Design procedures for three-stage CMOS operational transconductance amplifiers employing nested-Miller frequency compensation are presented in this paper. After describing the basic methodology on a Class-A topology, some modifications, to increase swing, slew-rate and current drive capability, are subsequently discussed for a Class-AB solution.

Proceeding of the thirteenth international symposium on Low power electronics and design - ISLPED '08, 2008
Optimization of power consumption is one of the main design challenges in today's low-power high-speed analog integrated circuits. In this paper, two popular techniques to stabilize two-stage operational amplifiers, namely Miller and cascode compensations are compared from power point of view.

Design guidelines for reversed nested miller compensation in three-stage amplifiers
IEEE Transactions on Circuits and Systems II: Analog and Digital Signal Processing, 2003The reversed nested Miller compensation technique applied to a three-stage operational amplifier is discussed in this paper and new and simple design equations, accurately predicting the loop-gain phase margin, are developed. Techniques for parasitic positive-zero cancellation are also investigated and compared.

Design considerations for fast-settling two-stage Miller-compensated operational amplifiers
2009 16th IEEE International Conference on Electronics, Circuits and Systems - (ICECS 2009), 2009The settling behavior of two-stage Miller-compensated operational amplifiers (op-amps) is investigated in this paper. The analysis aims to evaluate the real effectiveness of conventional design approaches for the settling performances optimization when op-amps are used in common SC circuits.
