Design methodology and advances in nested-Miller compensation
IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 2002The nested Miller compensation of three-stage amplifiers is reviewed by using a simple design-oriented approach. The method provides stable amplifiers by accurately controlling the overall phase margin as well as that of the internal loop. Furthermore, the use of nulling resistors to remove the RHP zeros is discussed and optimization criteria are ...

High performance reversed nested Miller frequency compensation
Analog Integrated Circuits and Signal Processing, 2015This paper presents an enhanced technique to improve frequency compensation in three stages operational transconductance amplifiers (OTA). Based on the reversed nested Miller technique, it uses a current subtractor in the common node of the Miller capacitors, thus significantly improving the gain-band width product (GBW) while ensuring unconditional ...

Active reversed nested Miller compensation for three-stage amplifiers
2006 IEEE International Symposium on Circuits and Systems, 2006A novel frequency compensation technique for three-stage amplifiers is introduced. Compared to the traditional reversed nested Miller compensation strategy, the proposed one exploits two active stages already included in the amplifier topology, thus no extra circuitry for its implementation is needed. The technique allows to remove the right-half-plane

Harmonic distortion in three-stage nested-Miller-compensated amplifiers
2004 IEEE International Symposium on Circuits and Systems (IEEE Cat. No.04CH37512), 2004A simplified approach for evaluating high-frequency distortion of three-stage amplifiers compensated with the nested-Miller technique is presented. The analysis exploits a proper amplifier modeling and, by suitable assumptions avoids complex methods based on the Volterra series, while providing simple equations useful even for design. Besides, the most

A two-stage amplifier with active miller compensation
2011 IEEE International Conference on Anti-Counterfeiting, Security and Identification, 2011A two-stage amplifier with active miller compensation is presented in this paper. Unlike the two-stage amplifier with conventional miller compensation, the proposed structure doesn't contain right half plane zero. What is more, a left half plane zero is created to cancel the first non-dominant pole.

Programmable bandwidth operational amplifier with negative miller compensation
2017 International Electrical Engineering Congress (iEECON), 2017This paper presents a novel technique to design a programmable bandwidth single-ended output CMOS operational amplifier using a serial digital interface. The circuit topology enables the programming of the value of a negative Miller capacitance around first amplification stage and programming of the value of a Miller capacitance around the second ...

Nested Miller compensation in low-power CMOS design
IEEE Transactions on Circuits and Systems II: Analog and Digital Signal Processing, 2001First, new stability conditions for low-power CMOS nested Miller compensated amplifiers are given in this brief. Then, an improved structure, which takes the advantages of a feedforward transconductance stage and a nulling resistor, is introduced. Experimental results prove that the proposed structure improves the frequency response, transient response,

An optimized Miller compensation based on voltage buffer
38th Midwest Symposium on Circuits and Systems. Proceedings, 2002An optimized compensation strategy for two-stage transconductance operational amplifiers adopting Miller compensation is presented. The compensation takes advantage of the finite output conductance of the buffer which is used to avoid the right half-plane zero. The proposed strategy allows compensation for the second pole due to the load capacitance to

Improving capacitive drive capability of miller compensated amplifier
Proceedings Norchip Conference, 2004., 2005This paper compares a well-known technique of Separating a capacitive load from the feedback path with a resistor to an alternative separation resistor technique and discusses limitations of both techniques. It is shown with small signal analysis und simulations that the suggested compensation technique has a bandwidth advantage over the traditional ...

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 ...
