Amplifier Design for Fast Settling Performance
نویسندگان
چکیده
A design strategy for minimizing a feedback amplifier’s step-response settling time is introduced. Central to this approach is the clear identification of the independent design parameters characterizing the amplifier and the introduction of a figure of merit for assessing the settling performance of an amplifier that is independent of power, supply voltage and capacitive loading. With this approach, the settling performance of a given amplifier architecture can be optimized and the relative performance of different amplifier architectures can be assessed. Emphasis in this paper is on the twostage operational amplifier architecture but the technique readily extends to other widely used operational amplifier structures.

Fast-Settling Amplifier Design Using Feedforward Compensation Technique
A new feedforward compensation amplifier architecture that provides very fast settling performance is introduced. The additional feedforward path introduces zeros in the open-loop transfer function which can be used to shape the overall frequency response. It is shown that a second-order bandpass feedforward path is useful for extending the unitygain-frequency of the overall amplifier. By choos...

High gain amplifiers with fast settling times are needed for high-speed data converter applications. A cascaded amplifier architecture is discussed that can make use of several architecturally identical amplifies to achieve the desired gain. Only one of the amplifiers has a gainbandwidth product requirement that is modestly higher than the rest to keep the overall structure stable in the presen...

Settling performance of operational amplifiers (opamps) is of great importance in analog signal-processing applications. Among different architectures, three-stage amplifiers are gaining more attention between analog circuit designers of modern technologies with small supply voltages where few devices can be stacked. Previous attempts to design and optimize a three-stage opamp based on settling...
