Reversed nested Miller compensation with current follower

ISCAS 2001. The 2001 IEEE International Symposium on Circuits and Systems (Cat. No.01CH37196), 2002
The reversed nested-Miller compensation technique is reviewed by using a simple design-oriented approach. A single current follower is also exploited to provide right-half-plane zero removal while allowing wide band and preserving output swing. Thanks to the small compensation capacitors employed, the approach is suited for integration.

Design methodology and advances in nested-Miller compensation

IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 2002
The 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, 2015
This 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, 2006
A 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), 2004
A 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, 2011
A 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), 2017
This 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, 2001
First, 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, 2002
An 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., 2005
This 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 ...
