    實(shí)現(xiàn)這一目標(biāo)的方法隨著時(shí)間的推移而發(fā)生了變化。最早使用的方法之一是直接補(bǔ)償技術(shù)，其中使用熱敏電阻、電容器和電阻器網(wǎng)絡(luò)直接控制振蕩器的頻率。溫度的變化會(huì)導(dǎo)致熱敏電阻發(fā)生變化，從而導(dǎo)致網(wǎng)絡(luò)的等效串聯(lián)電容發(fā)生變化——這反過來會(huì)改變晶體上的電容負(fù)載，從而導(dǎo)致頻率的變化振蕩器。

    當(dāng)前的方法將補(bǔ)償網(wǎng)絡(luò)和拉動(dòng)網(wǎng)絡(luò)集成到一個(gè)集成電路中，補(bǔ)償網(wǎng)絡(luò)的作用由一組運(yùn)算放大器發(fā)揮作用，這些運(yùn)算放大器相加在一起會(huì)在整個(gè)溫度范圍內(nèi)產(chǎn)生3階或5階函數(shù)。與間接補(bǔ)償方法一樣，該電壓用于驅(qū)動(dòng)變?nèi)荻O管，進(jìn)而改變振蕩器的輸出頻率。由于晶體特性的變化意味著不存在“一刀切”的功能，因此該解決方案是在TCXO的溫度測(cè)試期間得出的。使用兩個(gè)電容陣列將室溫下的頻率調(diào)整到標(biāo)稱值，然后在測(cè)試過程中獲得溫度補(bǔ)償功能所需的設(shè)置并存儲(chǔ)在片上存儲(chǔ)器中。

    TCXO晶振對(duì)工程師很有用，因?yàn)樗鼈兛梢栽谌魏蔚胤将@得比標(biāo)準(zhǔn)VCXO高10倍到40倍的溫度穩(wěn)定性，同時(shí)具有相同的功耗和電路板上的占位面積。TCXO彌合了標(biāo)準(zhǔn)XO或VCXO與OCXO之間的差距，后者更昂貴且需要更多功率才能運(yùn)行。技術(shù)的推動(dòng)力是降低功耗，當(dāng)然還有降低成本，因此TCXO為功率和成本敏感的應(yīng)用提供了良好的中檔解決方案。
