單極型管的單極放大電路，用場(chǎng)效應(yīng)管作為放大器件組成的放大電路，稱為場(chǎng)效應(yīng)管放大電路。場(chǎng)效應(yīng)管和雙極型晶體管一樣是電路的核心器件，在電路中起以小控大的作用。在場(chǎng)效應(yīng)管的放大電路中，為實(shí)現(xiàn)電路對(duì)信號(hào)的放大作用，要建立偏置電路以提供合適的偏置電壓，使場(chǎng)效應(yīng)管工作在特性的恒流區(qū)。

自給偏壓電路

N溝道耗盡型MOS管組成的共源極放大電路

自給偏壓電路

自給偏壓電路

場(chǎng)效應(yīng)管的柵極通過電阻Rg接地，源極通過電阻Rs接地。這種偏置方法靠漏極電流Id在源極電阻Rs上產(chǎn)生的電壓為柵源極提供一個(gè)偏置電壓Ugs，故稱為自偏壓電路。

場(chǎng)效應(yīng)管

場(chǎng)效應(yīng)管也是非線性器件，在輸入信號(hào)電壓很小的條件下，也可將其用小信號(hào)模型等效。與建立雙極型三極管小信號(hào)模型相似，將場(chǎng)效應(yīng)管也看成一個(gè)兩端口網(wǎng)絡(luò)，以結(jié)型場(chǎng)效應(yīng)管為例，柵極與源極之間為輸入端口，漏極與源極之間為輸出端口。無論是哪種類型的場(chǎng)效應(yīng)管，均可以認(rèn)為柵極電流為零，輸入端口視為開路，柵源極間只有電壓存在。

共源極

共源極場(chǎng)效應(yīng)管放大電路與雙極型管共射放大電路相比較，

共源極放大電路

共源極放大電路

共源極放大電路具有以下特點(diǎn)：輸入電阻，相當(dāng)于開路；輸出電阻由于并聯(lián)一個(gè)電阻Rds，因此輸出電阻較小。共源極場(chǎng)效應(yīng)管放大電路的微變等效電路相當(dāng)于一個(gè)電壓控制的電流源。

放大電路

共漏極放大電路又稱為源極輸出器或源極跟隨器，同樣具有與共集電極放大電路相同的特性：輸入電阻高、輸出電阻低和電壓放大倍數(shù)小于1并接近于1。
