傳感元件（變送器）將有用的物理信號轉換為電信號，例如：用于測量壓力的壓阻橋、用于檢測超聲波的壓電傳感器以及用于測量氣體濃度的電化單元等。傳感元件產生的電信號都很小，并且為非理想狀態(tài)，例如：溫度漂移和非線性傳輸函數等。

　　傳感器模擬前端（例如：德州儀器LMP91000）和傳感器信號調節(jié)器（例如：德州儀器PGA400/450），用于把這些傳感元件所產生的小信號放大到可用水平。PGA400/450包含完整的信號調節(jié)電路，以及可刺激傳感元件、管理功率并與外部控制器連接的一些電路。另外，如PGA400等器件還能夠對這些傳感元件的非理想狀態(tài)進行校準。

　　多模態(tài)信號調節(jié)

　　通常，為了實現信號調節(jié)或者更高級別的監(jiān)控，我們需要對多個傳感元件的輸出進行測量。例如，處理某個典型壓阻橋的輸出，便要求同時對橋和溫度傳感器的輸出進行測量。同樣，處理熱電偶的輸出，要求同時對該熱電偶和測量連接器溫度的傳感器的輸出進行測量。測量連接器溫度的目的是完成冷接點補償。同一個信號調節(jié)器對多個傳感元件進行處理的情況被稱作“多模態(tài)信號調節(jié)”。

　　混合信號信號調節(jié)

　　傳感器信號調節(jié)的另一個方面是發(fā)生信號調節(jié)的電域。德州儀器PGA309器件的電阻橋傳感元件的信號調節(jié)發(fā)生在模擬域內。在如PGA400等器件中，信號調節(jié)同時發(fā)生在模擬和數字域內。后一種情況被稱作“混合信號信號調節(jié)”。

　　混合信號調節(jié)器的一個關鍵組成部分是模數轉換器（ADC）。在信號達到智能補償模塊以前，兩個傳感元件始終都有獨立的信號通路。之后，該模塊組合這兩個信號，產生經過處理之后的輸出。
