Kukho izinto ezininzi ezibalulekileyo ekufuneka uzigcine engqondweni xa uyila i-amplifier yamanqanaba amaninzi.Nazi ezinye zezinto eziphambili ekufuneka uziqwalasele:

Inzuzo kunye neeMfuno zeBandwidth
Inyathelo lokuqala ekuyileni i-amplifier ye-multistage kukufumanisa inzuzo efunekayo kunye ne-bandwidth.Oku kuxhomekeke kwisicelo kunye neenkcukacha zokusebenza ezifunekayo.Inzuzo yenqanaba ngalinye kufuneka ikhethwe ukuhlangabezana nemfuno yokuzuza ngokubanzi, ngelixa i-bandwidth kufuneka ikhethwe ukuhlangabezana nemfuno yokuphendula rhoqo.
Igalelo kunye neMbeko yeZiphumo
Igalelo kunye nokuphazamiseka kokuphuma kwenqanaba ngalinye kufuneka kukhethwe ngononophelo ukuze kuqinisekiswe ukuhambelana okufanelekileyo kwizigaba ezandulelayo nezilandelayo.Oku kubalulekile ukunciphisa ukubonakalisa umqondiso kunye nokwandisa ugqithiso lwamandla phakathi kwesiteji.
I-Bias Voltage
Ukuthambekela okufanelekileyo kwinqanaba ngalinye kubalulekile ukuqinisekisa ukusebenza okuzinzileyo kunye nomgca.Iskimu sokuthambekela esikhethiweyo kufuneka sinikeze amanqanaba afunekayo akhoyo ngoku kunye nombane ngelixa unciphisa ukuchithwa kwamandla kunye nefuthe lobushushu.
Ingxolo kunye nokuGqwetha
I-multistage amplifiers yazisa ingxolo eyongezelelweyo kunye nokuphazamiseka xa kuthelekiswa ne-amplifiers eyodwa.Kufuneka kuthathelwe ingqalelo ukunciphisa ezi ziphumo ngokukhethwa kwecandelo elifanelekileyo, uyilo kunye nokukhusela.
Uzinzo
I-Multistage amplifiers iqhelekile kwi-oscillation, ngakumbi kwii-frequencies eziphezulu.Imbuyekezo efanelekileyo kunye nengxelo kufuneka isetyenziswe ukuqinisekisa ukusebenza okuzinzileyo kuluhlu olufunekayo lwamaza.
Isishwankathelo, ukuyila i-amplifier ye-multistage ifuna ukuqwalaselwa ngenyameko kwizinto ezininzi, kubandakanywa ukuzuza kunye neemfuno ze-bandwidth, igalelo kunye nokuphazamiseka kwemveliso, ukuxhatshazwa, ingxolo kunye nokuphazamiseka, kunye nokuzinza.Ngokuqwalasela ngokucophelela le miba, i-amplifier eyenziwe kakuhle ye-multistage inokubonelela ngokusebenza okuphezulu kunye nokuthembeka kwezicelo ezahlukeneyo.
