Long-term behavior of operational amplifiers
نویسندگان
چکیده
The voltage and current offsets of two typical precision operational amplifiers (OPAs) with BJT and FET input, respectively, were continuously measured for two years. The paper presents the experiment, explains the method of data analysis, and discusses the results. The long-term stability turns out to be limited mainly by random walk processes.

Equivalent Gain Analysis for Nonlinear Operational Amplifiers*
For low-voltage, low-power circuit design, the linear model for operational amplifiers is insufficient to accurately predict the static and dynamic behavior of the circuit. This paper introduces a nonlinear model for operational amplifiers based on amplifiers’ DC transfer characteristic. By using this nonlinear model, the behavior of an operational amplifier with feedback network can be describ...
متن کاملAnalysis of oil price behavior in the short term and long term based on the strategy of producers
The strategy are in the planning of oil price changes in the short and long term. Therefore, producers should seek to analyze the behavior of crude oil prices in the short and long term in order to adjust their plans. the price level in the oil market is associated with high fluctuations, many producers in the market seek to reduce exchange risk. This article aims to analyze the behavior of oil...
متن کاملThe Evolution of Long-term Care Programs; Comment on “Financing Long-term Care: Lessons From Japan”
The need for long-term care (LTC) represents a “new social risk,” one that overlaps with and complements systems of care that pre-date such programs, complicating LTC program design. This commentary expands on Ikegami’s discussion of how these structural factors must be accommodated, as well as historical and cultural factors that influence public expectations of such a...
متن کاملImpact of Fourth-Order Dispersion Coefficient on the Gain Spectrum and the Saturation Behavior of One-Pump Fiber Optical Parametric Amplifiers
In this paper, the gain spectrum and the saturation behavior of one-pump fiber optical parametric amplifiers (1-P FOPAs) are investigated by taking into account the fourth-order dispersion coefficient b4 in the analysis. The results show that it is necessary to consider b4 in the analysis when the wavelength difference between the signal and pump waves is large enough and/or whenever the pump w...
متن کاملImpact of Input Pump Profile on the Gain Spectrum and the Saturation Behavior of One-Pump Fiber Optical Parametric Amplifiers
In this article, the impact of input pump profile on the gain spectrum as well as the saturation behavior of one-pump fiber optical parametric amplifiers (FOPAs) is investigated. Since in practical circumstances, pump sources used for FOPAs have Lorentz-Gaussian profile instead of Gaussian, a more realistic case is considered for simulating FOPAs in this article. The results of simulations for ...
