Single Miller capacitor compensated multistage amplifiers for large capacitive load applications

2004 IEEE International Symposium on Circuits and Systems (IEEE Cat. No.04CH37512), 2004
This work presents two compensation techniques for low-voltage three-stage amplifiers driving large capacitive loads: single Miller capacitor compensation (SMC) and single Miller capacitor feedforward compensation (SMFFC). They are implemented in amplifiers fabricated in standard 0.5 /spl mu/m CMOS technology.

A Super-bandwidth Three-stage Amplifier with Single Miller-capacitor Compensation

2007 International Workshop on Electron Devices and Semiconductor Technology (EDST), 2007
A 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

Single Miller capacitor frequency compensation technique for low-power multistage amplifiers

IEEE Journal of Solid-State Circuits, 2005
Due to the rising demand for low-power portable battery-operated electronic devices, there is an increasing need for low-voltage low-power low-drop-out (LDO) regulators. This provides motivation for research on high-gain wide-bandwidth amplifiers driving large capacitive loads.

Active capacitor multiplier in Miller-compensated circuits

IEEE Journal of Solid-State Circuits, 2000
A technique is presented whereby the compensating capacitor of an internally compensated linear regulator, Miller-compensated two-stage amplifier, is effectively multiplied. Increasing the capacitance with a current-mode multiplier allows the circuit to occupy less silicon area and to more effectively drive capacitive loads.

Nested miller active-capacitor frequency compensation for low-power three-stage amplifiers

2008 IEEE International Conference on Electron Devices and Solid-State Circuits, 2008
A 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

A new Architecture for two-stage OTA with no-miller capacitor compensation

2012 IEEE International Conference on Circuits and Systems (ICCAS), 2012
A new Architecture for two-stage Operational Transconductance Amplifier is presented. In this new structure the pole-zero cancellation technique is used to increase the amplifier band width. The proposed architecture uses a very simple circuit implementation scheme to create a feed-forward path in order to make a zero in voltage transfer function.

A Fast Settling Low Dropout Linear Regulator with Single Miller Compensation Capacitor

2005 IEEE Asian Solid-State Circuits Conference, 2005
A 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).

Enhanced DC gain amplifier using no miller capacitor feedforward compensation

2013 IEEE 4th Latin American Symposium on Circuits and Systems (LASCAS), 2013
This 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 ...
