Maxaan samayn karaa si aan u hagaajiyo MOSFET-kayga oo si xun u kululaanaysa?

Wareegyada sahayda korontada, ama wareegyada sahayda korantada ee goobta kicinta, si lama huraan ah loo isticmaaloMOSFET-yada, kuwaas oo noocyo badan leh oo leh hawlo badan. Beddelka sahayda korontada ama codsiyada kicinta, waa dabiici in la isticmaalo shaqadeeda beddelka.

Iyadoo aan loo eegin nooca N-nooca ama P-noocaMOSFET, mabda'a asal ahaan waa isku mid, MOSFET waxaa lagu daraa iridda dhamaadka bonding ee hadda si loo habeeyo dhinaca wax soo saarka ee biya shubka hadda, MOSFET waa qalab korantada-control oo ku salaysan hadda lagu daray albaabka on the Ku-dhaqanka sifooyinka aaladda, uma nugulna u beddelashada sida transistor-ka oo kale sababta oo ah saldhigga hadda socda ee uu keenay saamaynta kaydinta kharashka togan, sidaas darteed, codsiga beddelka, heerka beddelka MOSFET waa inuu ka dhaqso badan yahay kan transistor. Heerka beddelka waa in uu ka dheereeyaa saddex geesoodka.

MOSFETsababaha kululaynta-yar ee hadda

1, mabda'a wareegga ee dhibaatadu waa in MOSFET ay u ogolaato inay ku shaqeyso xaalada toosan ee hawlgalka, halkii ay ka ahaan lahayd xaalada beddelka. Tani waxay sidoo kale sabab u tahay kulaylka MOSFET. Haddii beddelka N-MOS, danab-shaqeedka G-heer ka badan sahayda beddelka dhowr V, si ay si buuxda u shid iyo off, P-MOS waa habka kale. Aan si buuxda u damin oo khasaaruhu aad buu u weyn yahay taasoo keentay in korontadu soo baxdo, wareegga u dhigma ee DC-ga sifo waa ka weyn yahay, khasaaraha waa la ballaariyay, sidaas darteed U * I sidoo kale waa la ballaariyay, dhimashadu waxay u taagan tahay kulayl. Tani sidoo kale waa wareegga kontoroolka barnaamijka naqshadeynta ee aadka looga fogaaday.

2, inta jeer waa mid aad u sarreeya, inta badan mararka qaarkood aad u badan raadinta mugga qumman, taasoo keentay kor u kaca soo noqnoqda, MOSFET ee ballaarinta isticmaalka, sidaas darteed kulaylku sidoo kale wuu kordhay.

3, ma samayn ku filan barnaamijka naqshadaynta kulaylka ka saarida, hadda aad buu u sarreeyaa, MOSFET qiimaha hadda jira, guud ahaan waa in la ilaaliyo kulaylka wanaagsan ee ka saarista waa la samayn karaa. Sidaa darteed, aqoonsigu wuu ka hooseeyaa kan hadda sarreeya, sidoo kale waxay u badan tahay inuu kululeeyo si ka sii daran, waa inuu ahaadaa mid ku filan inuu caawiyo kulaylka.

4, MOSFET xulashada model ma aha mid sax ah, awoodda wax soo saarku sax maaha, iska caabbinta MOSFET aan xisaabta lagu darin, taasoo keentay ballaarinta is-beddelka dabeecadda.
