VGA主要分為開(kāi)環(huán)和閉環(huán)兩種結(jié)構(gòu)。一種常見(jiàn)的開(kāi)環(huán)結(jié)構(gòu)是文獻(xiàn)[1]采用的Gilbert結(jié)構(gòu)，如圖2所示電路。Ms上加一個(gè)基準(zhǔn)電壓，電壓Vc控制耦合電流的大小，起到改變?cè)鲆娴淖饔?。但是此結(jié)構(gòu)電路堆疊了四層電路，限制了輸出電壓的擺幅，而且此電路不能實(shí)現(xiàn)指數(shù)增益的控制。這些運(yùn)用最廣泛的開(kāi)環(huán)結(jié)構(gòu)中，可變?cè)鲆娣糯笃髦饕诤?jiǎn)單差分，或者是偽差分對(duì)，使用源極反饋技術(shù)，模擬乘法器和使用二極管連接的MOS管作為負(fù)載等技術(shù)。這些結(jié)構(gòu)最大的問(wèn)題就是線(xiàn)性度和失真度的問(wèn)題。<br /> 因?yàn)樨?fù)反饋電路具有穩(wěn)定輸出，降低非線(xiàn)性失真的作用，所以閉環(huán)結(jié)構(gòu)呈現(xiàn)更好的線(xiàn)性度。常見(jiàn)的閉環(huán)電路結(jié)構(gòu)中的VGA使用電阻陣列實(shí)現(xiàn)增益控制，例如將電阻和MOS管串聯(lián)，控制MOS管開(kāi)關(guān)的通斷狀態(tài)實(shí)現(xiàn)阻值的變化，進(jìn)而改變放大器的增益。因?yàn)槔^承電路中的電阻、MOS管開(kāi)關(guān)都受到工藝、電壓、溫度的影響，難以實(shí)現(xiàn)精確的阻值，所以PGA的增益精度有限。文獻(xiàn)[9]使用電流分割技術(shù)，實(shí)現(xiàn)了精確的增益控制，文獻(xiàn)[10]對(duì)電阻網(wǎng)絡(luò)進(jìn)行了改進(jìn)，但是這些電路復(fù)雜，額外電路也增加了功耗。這里在沒(méi)有增加任何設(shè)計(jì)復(fù)雜性的情況下，實(shí)現(xiàn)了較為精確的增益控制。</span>
