Ma waxaad raadineysaa inaad si fiican u maamusho MOSFET amplifiers? Waxaad joogtaa meesha saxda ah Hagahan dhammaystiran waxa uu wax kasta ka kala jebiyaa fikradaha aasaasiga ah ilaa codsiyada cidhiidhiga ah, isaga oo kaa caawinaya inaad fahamto noocyada kala duwan ee cod-weyneyaasha MOSFET iyo hirgelintooda la taaban karo.
Fahamka MOSFET Amplifier Aasaaska
Cod-weyneyaasha MOSFET waxay wax ka beddeleen qalabka elektaroonigga ah ee casriga ah, iyagoo bixinaya waxqabad heersare ah marka la eego hufnaanta awoodda, jawaabta soo noqnoqda, iyo fududaanta wareegga. Kahor intaanan quusin noocyo gaar ah, aan fahanno waxa ka dhigaya cod-weyneyaasha MOSFET mid gaar ah.
Faa'iidooyinka ugu muhiimsan ee MOSFET Amplifiers
- Wax-soo-gelinta sare marka la barbar dhigo cod-weyneyaasha BJT
- Deganaanshaha kulaylka wanaagsan
- Tilmaamaha qaylada hoose
- Sifooyin beddelasho oo heer sare ah
- Qallooca ugu yar ee soo noqnoqda sare
Cod-weyneeye Ilaha Guud: Dhismaha Aasaaska ah
Cod-weyneyeeyaha isha guud (CS) waa MOSFET oo u dhiganta qaabeynta BJT-ga hawada sare. Waa nooca cod-weyneeye MOSFET-ka ugu isticmaalka badan iyadoo ay ugu wacan tahay kala-duwanaanshaha iyo sifada waxqabadkeeda.
