Ni ubuhe buryo bukoreshwa na MOSFETS?

MOSFETSByakoreshejwe cyane. Noneho imiyoboro minini nini ihuriweho ikoreshwa MOSFET, imikorere yibanze na transistor ya BJT, irahindura kandi ikongerwaho. Ahanini triode ya BJT irashobora gukoreshwa aho ishobora gukoreshwa, kandi hamwe na hamwe imikorere iruta triode.

 

Kwiyongera kwa MOSFET

MOSFET na BJT triode, nubwo byombi byongera ibikoresho bya semiconductor, ariko ibyiza byinshi kuruta triode, nko kwinjiza ibintu byinshi, inkomoko yikimenyetso hafi ya ntakigezweho, ibyo bikaba bifasha gutezimbere ibimenyetso byinjira. Nigikoresho cyiza nkicyiciro cyinjiza amplifier, kandi gifite ibyiza byurusaku ruke hamwe nubushyuhe bwiza. Bikunze gukoreshwa nkibibanziriza amajwi yongerera amajwi. Nyamara, kubera ko ari igikoresho kigenzurwa na voltage igezweho, umuyoboro wamazi ugenzurwa na voltage iri hagati y irembo, coeffisiyoneri ya amplification ya transconductance yumurongo muke ntabwo ari nini, kubwibyo ubushobozi bwo kongera imbaraga ni bubi.

 

Ingaruka zo guhindura MOSFET

MOSFET ikoreshwa nka elegitoroniki ya elegitoronike, kubera gusa kwishingikiriza gusa kuri polyon ya convoyeur, ntahantu nka BJT triode bitewe nubu shingiro shingiro hamwe ningaruka zo kubika amafaranga, bityo umuvuduko wo guhinduranya MOSFET wihuta kuruta triode, nkumuyoboro uhinduranya ni Byakoreshejwe Kuri Byinshi-Byinshi-Ibihe, nko guhinduranya amashanyarazi akoreshwa muri MOSFET murwego rwo hejuru-rwinshi rwakazi. Ugereranije na BJT triode yahinduwe, MOSFET ihindura irashobora gukora kuri voltage ntoya ningaruka, kandi biroroshye guhuza kuri wafer ya silicon, kuburyo ikoreshwa cyane mumirongo minini ihuriweho.

Ni ubuhe buryo bwo kwirinda iyo ukoreshaMOSFETS?

MOSFETs iroroshye kurusha triode kandi irashobora kwangizwa byoroshye no kuyikoresha nabi, bityo rero ugomba kwitondera bidasanzwe mugihe uyikoresheje.

(1) Birakenewe guhitamo ubwoko bukwiye bwa MOSFET mubihe bitandukanye byo gukoresha.

. Cyane cyane iyo gusudira irembo ryakingiwe MOSFET, ukurikije isoko - gahunda ikurikiranye yo gusudira, nibyiza gusudira nyuma yumuriro. Imbaraga z'icyuma cyo kugurisha kugeza 15 ~ 30W zirakwiye, igihe cyo gusudira ntigishobora kurenza amasegonda 10.

. Iyo ikuweho, birakenewe kuzenguruka electrode mbere yo kuyikuramo kugirango wirinde irembo rirenze.

(7) Iyo ukoreshaMOSFETShamwe na substrate iyobora, substrate iyobora igomba guhuzwa neza.
