Enhanced DC gain amplifier using no miller capacitor feedforward compensation
2013 IEEE 4th Latin American Symposium on Circuits and Systems (LASCAS), 2013This paper presents an operational transconductance amplifier that uses current mirrors to add a feedforward path in order to do frequency compensation with no miller capacitor. A gain enhancement is achieved because the use of current mirrors reduces the number of the conductances that are connected to the output, increasing output impedance ...

A Super-bandwidth Three-stage Amplifier with Single Miller-capacitor Compensation
2007 International Workshop on Electron Devices and Semiconductor Technology (EDST), 2007A novel super-bandwidth three-stage amplifier with a new stability method are proposed in this paper. It could produce two left-half-plane zeros to compensate the two non-dominant poles and the dominant pole, which makes the amplifier had very large bandwidth and good phase margin. Moreover, only one Miller capacitor is required, and consumes not large

Accurate distortion modeling of feedback amplifier with Miller compensation is the main subject of this paper. Inspired by traditional Rosenstark method, a nonlinear signal-flow-based method has been developed. Based on the proposed method, the nonlinear coefficients of each gain stage can be evaluated exactly and the rules of cascading, feedback can ...

A Fast Settling Low Dropout Linear Regulator with Single Miller Compensation Capacitor
2005 IEEE Asian Solid-State Circuits Conference, 2005A 1.8-V, 150-mA fast settling low dropout linear regulator (LDO) with single Miller compensation capacitor is presented. By utilizing the digital-controlled dynamic bias circuit to track the output current, the proposed LDO provides fast settling time for the output capacitors with low and high equivalent series resistance (ESR).

Nested miller active-capacitor frequency compensation for low-power three-stage amplifiers
2008 IEEE International Conference on Electron Devices and Solid-State Circuits, 2008A new frequency compensation technique for low-power, area-efficient multistage amplifiers is introduced in this work. By utilizing active capacitors to realize the compensation network in a nested way, two inverting gain stages can be used as the second and third gain-stages. The proposed scheme reaches better bandwidth-to-power and slew-rate-to-power

This paper introduces a new effective single-Miller capacitor compensation topology for three-stage amplifiers with very large capacitive loads, realized through an active-feedback capacitor together with an inner half-feedforward stage. Moreover, an optimized design strategy which profitably exploits the two left half-plane zeros is presented.

In this paper, design of a new three stage amplifier is inspected and presented simply through the graph space. Indeed, after changing the signal flow graph of the DACFC amplifier using graph rules and design analysis based on graph algebra, a new design example of DACFC+ is presented, which decreases the compensation capacitor or ...
