【別讓 OPA 輸入電容成為穩定性＆相位餘裕殺手！】

輸入電容可能會成為高阻抗和高頻運算放大器 (OPA) 應用的一個主要規格。值得注意的是，當光電二極體的結電容較小時，運算放大器的輸入電容會成為「雜訊」和「頻寬」問題的主導因素。

運算放大器的輸入電容和回饋電阻在放大器的響應中產生一個極點，進而影響穩定性並增加較高頻率下的雜訊增益。因此，穩定性和相位餘裕可能會降低，輸出雜訊可能會增加。

以往一些CDM (差模電容) 測量技術依據的是高阻抗反相電路、穩定性分析以及雜訊分析，方法非常繁瑣——檢測 CDM 的傳統方法是間接測量，該方法依賴於「相位裕度的降低」，且因並聯使用 CCM– 等其他電容而變得更複雜。

現在，有了新的解決方案。

About author
2002年，憑藉獨特敏銳度察覺到電子業界需求，《COMPOTECHAsia電子與電腦》於中國大陸取得《COMPOTECHChina》月刊發行權，為初到海外發展及當地讀者出具最具前瞻性且中肯的觀察，具有相當影響力，也成為一流國際大廠競相展示研發心血的首選。 2006年，有鑑於網路環境日趨成熟，《COMPOTECHAsia電子與電腦》再度領先同業，首創線上視頻平台CTOV (COMPOTECH Online Video)。自此，成為整合紙本、網站、電子報及線上視頻的全方位媒體。 2016年，為貫徹市場應用及開發技術的連結並擴大群眾基礎，陸續展開 Facebook、Twitter、LinkedIn 等社群平台經營。 「就市論勢、就勢論市」是我們的信念。我們將於每週一、三、五下午在 FB 分享生活中隨處可見的科普知識，以平易近人的方式，用不一樣的角度觀察市場趨勢和技術走向，並不定時穿插轉載網路精彩佳作或趣聞。記得設為「搶先看」哦！ “COMPOTECHAsia/ China” issue on 8th monthly. It is the dependent media which focuses on electronic industry situation, end user market, and technology trend. The monthly magazine has become the main channel to get professional information for engineers, purchaser, R&D employees and decision-making management. We perceived the demand of electronic industry and strive to get the distribution rights of “China Edition” in Mainland China in 2002. It gives a lot of prospective and proper observation for the overseas workers and local readers. Gradually, COMPOTECH is getting to be the powerful. Nowadays, COMPOTECH is the first-choice platform for the first-class firms to display their R&D results. Furthermore, in 2006, we were ahead of our competitors to build the CTOV platform (COMPOTECH Online Video) due to the mature internet environment. Since then, COMPOTECH has become the integrated media. For having a thorough knowledge of market applications and technology migration, as well as expanding the base of the masses, we begin to manage the Facebook, Twitter and LinkedIn etc. in 2016.
智能系統設計／應用工程師、產品／專案開發主管、元器件／零組件／準系統採購者的交流園地，於每週一、三、五下午分享【科技應用取向】的趨勢議題。
