5. 集成运算放大器

集成运算放大器是一种把多级直流放大器做在一个集成片上，只要在外部接少量元件就能完成各种功能的器件。因为它早期是用在模拟计算机中做加法器、乘法器用的，所以叫做运算放大器。

6. 振荡器

不需要外加信号就能自动地把直流电能转换成具有振幅和频率的交流信号的电路就称为振荡电路或振荡器。这种现象也叫做自激振荡。或者说，能够产生交流信号的电路就叫做振荡电路。

一个振荡器包括三部分：放大器、正反馈电路和选频网络。放大器能对振荡器输入端所加的输入信号予以放大使输出信号保持恒定的数值。正反馈电路保证向振荡器输入端提供的反馈信号是相位相同的，只有这样才能使振荡维持下去。选频网络则只允许某个特定频率f0能通过，使振荡器产生单一频率的输出。

振荡器能不能振荡起来并维持稳定的输出是由以下两个条件决定的;一个是反馈电压Uf和输入电压 Ui要相等，这是振幅平衡条件。二是 Uf 和 Ui 相位相同，这是相位平衡条件，也就是说保证是正反馈。一般情况下，振幅平衡条件往往容易做到，所以在判断一个振荡电路能否振荡，主要是看它的相位平衡条件是否成立。

振荡器按振荡频率的高低可分成超低频（ 20赫以下）、低频（ 20赫～ 200千赫）、高频（200千赫～ 30兆赫）和频（ 10兆赫～ 350兆赫）等几种。按振荡波形可分成正弦波振荡和非正弦波振荡两类。

正弦波振荡器按照选频网络所用的元件可以分成 LC 振荡器、 RC振荡器和石英晶体振荡器三种。石英晶体振荡器有很高的频率稳定度，只在要求很高的场合使用。在一般家用电器中，大量使用着各种 LC振荡器和 RC 振荡器。

6.1 LC振荡器

LC 振荡器的选频网络是LC 谐振电路。它们的振荡频率都比较高，常见电路有 3 种。

1） 变压器反馈 LC 振荡电路
