宽带小信号放大电路研究
摘要
本题以宽带小信号放大电路为研究背景，因此设计实现宽带小信号放大电路的高增益、低噪声、高稳定等工作性能为基本出发点。在深入了解宽带小信号放大电路的基础上，研究分析宽带小信号放大电路的增益、带宽、失调电压、失调电流等指标，用宽带小信号放大电路设计。
在宽带小信号放大电路的选取上，选择最为常用的电压反馈型和电流反馈型运算放大电路两种进行研究。通过理论分析，进行电路设计，焊接并调试各放大电路，使用频谱仪测出增益、带宽等指标。在放大微弱信号的过程中，必然还会附加一些额外的误差，特别是放大电路引起的输出失调电压和失调电流等非常严重，且易受外界条件的影响。使用TINA仿真软件进行设计电路仿真，计算分析理论结果。为了验证理论设计的可行性，通过实际焊接调试电路，使用频谱仪对电路的输出电压等进行测试计算，验证所设计的电路指标，进一步验证理论设计电路的正确性和可行性。
