Ukucatshangelwa Kwedizayini Yezikhulisamandla ze-Multistage

Kunokucatshangelwa okuningana okubalulekile okufanele ukukhumbule lapho uklama i-multistage amplifier.Nazi ezinye zezinto ezibalulekile okufanele zicatshangelwe:

Cela Ikhotheshini Manje Yokwenziwa Kwe-PCB Nokuhlanganisa

I-Gain and Bandwidth Izidingo

Isinyathelo sokuqala sokuklama i-multistage amplifier ukucacisa inzuzo edingekayo kanye nomkhawulokudonsa.Lokhu kuncike kuhlelo lokusebenza kanye nemininingwane yokusebenza edingekayo.Inzuzo yesigaba ngasinye kufanele ikhethwe ukuze kuhlangatshezwane nemfuneko yokuzuza iyonke, kuyilapho umkhawulokudonsa kufanele ukhethwe ukuhlangabezana nemfuneko yokuphendula imvamisa.

Okokufaka nokuphumayo

I-impedance yokufaka nokuphumayo kwesiteji ngasinye kufanele kukhethwe ngokucophelela ukuze kuqinisekiswe ukuhambisana okufanele kwezigaba ezedlule nezilandelayo.Lokhu kubalulekile ukuze kuncishiswe ukuboniswa kwesignali nokwandisa ukudluliswa kwamandla aphakathi kwesiteji.

I-Bias Voltage

Ukuchema okufanele kwesigaba ngasinye kubalulekile ukuze kuqinisekiswe ukusebenza okuzinzile nokulandelanayo.Uhlelo lokuchema olukhethiwe kufanele lunikeze amazinga adingekayo athule amanje kanye ne-voltage kuyilapho kunciphisa ukuchithwa kwamandla kanye nemiphumela yokushisa.

Umsindo nokuhlanekezela

Ama-amplifiers e-Multistage ethula umsindo owengeziwe kanye nokuhlanekezela uma kuqhathaniswa nezikhulisi zesiteji esisodwa.Kufanele kuqashelwe ukuze kuncishiswe le miphumela ngokukhetha ingxenye efanele, ukwakheka kanye nokuvikela.

Ukuzinza

Ama-amplifiers e-Multistage athambekele ekutheni ama-oscillation, ikakhulukazi kumafrikhwensi aphezulu.Isinxephezelo esifanele kanye nempendulo kufanele kusetshenziswe ukuze kuqinisekiswe ukusebenza okuzinzile phezu kwebanga lefrikhwensi oyifunayo.

Kafushane, ukuklama i-multistage amplifier kudinga ukucatshangelwa ngokucophelela kwezici eziningi, okuhlanganisa izinzuzo nezidingo zomkhawulokudonsa, ukuvimbela okokufaka nokukhiphayo, ukuchema, umsindo nokuhlanekezela, nokuzinza.Ngokucabangela lezi zici ngokucophelela, i-amplifier ye-multistage eklanywe kahle inganikeza ukusebenza okuphezulu nokuthembeka kwezinhlelo zokusebenza ezihlukahlukene.

Amaqiniso asheshayo nge-NeoDen
