模擬前端

模擬前端（analog front-end，簡稱AFE），也稱為模擬前端控制器（analog front-end controller，簡稱AFEC）是為了特定應用所開發的模擬訊號調整電路，其中包括感測用的模擬放大器（多半是運算放大器）、濾波電路，也有可能有針對感測器的特殊應用集成電路、射頻接收器，其目的是提供可以組態，可調整的電子功能方塊，可以做為天線感測器、模擬數碼轉換器甚至是單晶片的介面電路。

無線電接收器中的射頻模擬前端有時也會稱為射頻前端（英語：RF front end）^[1]。

模組

在許多的模擬系統和數碼系統中，會使用模擬前端硬件模組做為介面電路，提供硬件的模組化。有許多IC廠商有針對不同的應用製作模擬前端晶片，例如德州儀器針對健康監控的模擬前端晶片ADS1298、AFE4400和AFE4490^[2]^[3]。Atmel有針對智能電表的模擬前端晶片^[4]。亞德諾半導體也針對測試和量測應用開發了CN0209模擬前端晶片^[5]。
