摘要
简要介绍了运算放大器电路包含的噪声类型。运用标准的电路理论和噪声模型,计算运算放大器电路的噪声。结合反相、同相和差分输入的运算放大器电路分析举例,讨论了推算运算放大器电路噪声的方法。最后,给设计人员提供了有关噪声设计的建议和方法。
Different noise types in operational amplifier （op-amp） circuits are described. Standard circuit theory and noise models are used to calculate noises in op-amp circuits. With inverting, noninverting and differential opamp circuits as examples,methods to noise calculations are illustrated. Finally,useful advices and techniques for noise design are provided.
