Transient Response Enhancement with Fast Transient Controller for Capacitor-Less LDO Regulator
Applied Mechanics and Materials, 2014This paper presents a capacitor-less CMOS low dropout regulator (LDO) with a push-pull class AB amplifier, and a fast transient controller to achieve a better transient response. The undershoot/overshoot voltage and the settling time are effectively reduced.

Response of power cables to fast transient loads
Conference Record of the 2004 IEEE Industry Applications Conference, 2004. 39th IAS Annual Meeting., 2004The most accepted standards for ampacity of power cables consider only steady-state loads. In "Cable Sizing for Fast Transient Loads," R.E. Henry, the transient temperature response of cables is addressed when installed in tray and conduits and undergoing fast transient heating. Herein, the fast transient work is extended by presenting how power cables

A Portable Fast-Response Transient-Voltage Counter
IEEE Transactions on Power Apparatus and Systems, 1965A battery-powered solid-state 6-channel transient-voltage counter was developed which can detect transient voltages with durations as short as 20ns. This counter is sensitive to transient voltages of both polarities and has threshold levels from 50 to 300 volts, which can be altered by either internal biasing or external attenuators. It weighs about 13.

High accuracy LDO regulator with fast transient response
TENCON 2008 - 2008 IEEE Region 10 Conference, 2008This paper presents a modified single Miller capacitor feed forward compensation design for regulators resulting in a linear LDO (low dropout) regulator whose performance is independent of the off-chip capacitor and its ESR (equivalent series resistor). The proposed compensation method ensures the stability of the feedback loop and the sufficient phase

An investigation on control strategies for fast transient response of SMPS
2008 IEEE Conference on Innovative Technologies in Intelligent Systems and Industrial Applications, 2008This paper presents a thorough literature reviews of control methods to improve transient response in switch mode power supply (SMPS). A fast transient response to a step load change is very essential in a power supply. The transient response can be improved by means of feedback control method.

Fast transient response capacitorless DC-DC converter
2017 Brazilian Power Electronics Conference (COBEP), 2017This paper features a hybrid (switched-mode and linear-mode) and capacitorless DC-DC converter, retaining its output characteristic of the voltage source type. The converter was designed by joining a switched-mode converter and a linear amplifier connected in parallel.

A Fast Fullchip Transient Response Estimation Technique
2011Circuit Simulation has long been a dependable technique for design engineers for functional testing before a circuit is taken to silicon. But as we move into deep sub-micron technologies, chips are becoming more complex and denser. The dense power grid adds to long simulation runtime rendering fullchip simulations difficult and computationally ...

Response of fast-reactor core subassemblies to pressure transients
Nuclear Engineering and Design, 1982Abstract An Arbitrary Lagrangian-Eulerian (ALE) finite element method for analyzing the transient, nonlinear fluid-structure interaction in fast-reactor core subassemblies is presented. The method combines the basic attributes of the finite element technique — namely, ease in modeling complex geometries and in mixing fluid elements with structural ...

Low power LDO with fast load transient response based on quick response circuit
2009 IEEE International Symposium on Circuits and Systems, 2009In this work, we propose a design technique of low power fully CMOS low-dropout voltage regulator (LDO) based on quick response (QR) circuit to improve the load transient response. Implemented in 0.18µm CMOS technology, the LDO with proposed QR circuit can achieve a fast load transient responses with less transient overshoot or undershoot when driving ...

A Linear Robust State Estimator with Fast Transient Response
1986 American Control Conference, 1986A new recursive linear filter is considered for the estimation of the unknown states of a dynamic system. In general, this new filter has fast convergence rate and lower RMS error than the conventional Kalman filter during the transient phase. It becomes a Wiener filter as time increases.
