5. 集成運(yùn)算放大器

集成運(yùn)算放大器是一種把多級(jí)直流放大器做在一個(gè)集成片上，只要在外部接少量元件就能完成各種功能的器件。因?yàn)樗缙谑怯迷谀M計(jì)算機(jī)中做加法器、乘法器用的，所以叫做運(yùn)算放大器。

6. 振蕩器

不需要外加信號(hào)就能自動(dòng)地把直流電能轉(zhuǎn)換成具有振幅和頻率的交流信號(hào)的電路就稱為振蕩電路或振蕩器。這種現(xiàn)象也叫做自激振蕩?；蛘哒f(shuō)，能夠產(chǎn)生交流信號(hào)的電路就叫做振蕩電路。

一個(gè)振蕩器包括三部分：放大器、正反饋電路和選頻網(wǎng)絡(luò)。放大器能對(duì)振蕩器輸入端所加的輸入信號(hào)予以放大使輸出信號(hào)保持恒定的數(shù)值。正反饋電路保證向振蕩器輸入端提供的反饋信號(hào)是相位相同的，只有這樣才能使振蕩維持下去。選頻網(wǎng)絡(luò)則只允許某個(gè)特定頻率f0能通過(guò)，使振蕩器產(chǎn)生單一頻率的輸出。

振蕩器能不能振蕩起來(lái)并維持穩(wěn)定的輸出是由以下兩個(gè)條件決定的;一個(gè)是反饋電壓Uf和輸入電壓 Ui要相等，這是振幅平衡條件。二是 Uf 和 Ui 相位相同，這是相位平衡條件，也就是說(shuō)保證是正反饋。一般情況下，振幅平衡條件往往容易做到，所以在判斷一個(gè)振蕩電路能否振蕩，主要是看它的相位平衡條件是否成立。

振蕩器按振蕩頻率的高低可分成超低頻（ 20赫以下）、低頻（ 20赫～ 200千赫）、高頻（200千赫～ 30兆赫）和頻（ 10兆赫～ 350兆赫）等幾種。按振蕩波形可分成正弦波振蕩和非正弦波振蕩兩類(lèi)。

正弦波振蕩器按照選頻網(wǎng)絡(luò)所用的元件可以分成 LC 振蕩器、 RC振蕩器和石英晶體振蕩器三種。石英晶體振蕩器有很高的頻率穩(wěn)定度，只在要求很高的場(chǎng)合使用。在一般家用電器中，大量使用著各種 LC振蕩器和 RC 振蕩器。

6.1 LC振蕩器

LC 振蕩器的選頻網(wǎng)絡(luò)是LC 諧振電路。它們的振蕩頻率都比較高，常見(jiàn)電路有 3 種。

1） 變壓器反饋 LC 振蕩電路
