Kuki MOSFETs voltage igenzurwa?

MOSFETs (Metal Oxide Semiconductor Field Effect Transistors) yitwa ibikoresho bigenzurwa na voltage ahanini kubera ko ihame ryimikorere ryabo rishingiye cyane cyane kugenzura imiyoboro yumuryango (Vgs) hejuru yumuyoboro wamazi (Id), aho kwishingikiriza kumuyoboro kugirango ubigenzure, nkuko ni ikibazo na bipolar transistors (nka BJTs). Ibikurikira nubusobanuro burambuye bwa MOSFET nkigikoresho kigenzurwa na voltage:

Ihame ry'akazi

Igenzura ry'umuvuduko w'amarembo:Umutima wa MOSFET uri mumiterere iri hagati y irembo ryayo, isoko namazi, hamwe nigice cyiziritse (mubisanzwe dioxyde de silicon) munsi y irembo. Iyo voltage ishyizwe kumuryango, umurima wamashanyarazi uremwa munsi yigitereko, kandi uyu murima uhindura imikorere yikibanza kiri hagati yisoko n'amazi.

Imiyoboro Yayobora:Kuri N-umuyoboro MOSFETs, mugihe amarembo ya voltage ya Vgs ari hejuru bihagije (hejuru yagaciro kihariye bita voltage voltage Vt), electron zo mubwoko bwa P munsi ya irembo zikururwa munsi yurwego rwiziritse, rukora N- andika umuyoboro uyobora utanga imiyoboro hagati yisoko n'amazi. Ibinyuranye, niba Vgs iri munsi ya Vt, umuyoboro uyobora ntabwo washizweho kandi MOSFET iri guhagarara.

Kuramo igenzura:ingano yumuyoboro wamazi Id igenzurwa cyane cyane na voltage yumuryango Vgs. Hejuru ya Vgs, nini yagutse umuyoboro uyobora, kandi nini nini ya Id. Iyi sano ituma MOSFET ikora nkigikoresho cya voltage igenzurwa nubu.

Ibyiza bya Piezo

Kwinjiza Byinshi:Kwinjiza inzitizi ya MOSFET ni ndende cyane kubera kwigunga kw'irembo hamwe n'akarere kavomamo akoresheje urwego rukingira, kandi irembo ryinjira hafi ya zeru, ibyo bikaba ari ingirakamaro mumuzunguruko aho hakenewe inzitizi nyinshi.

Urusaku ruto:MOSFETs itanga urusaku ruto ugereranije mugihe cyo gukora, ahanini biterwa no kwinjiza kwinshi kwinshi hamwe nuburyo bwo gutwara ibintu bitwara unipolar.

Umuvuduko wihuse:Kubera ko MOSFETs ari ibikoresho bigenzurwa na voltage, umuvuduko wabo wo guhinduranya mubisanzwe byihuta kurenza ibya bipolar transistors, bigomba kunyura muburyo bwo kubika no kurekura mugihe cyo guhinduranya.

Gukoresha ingufu nke:Muri leta, kurwanya imiyoboro y'amazi (RDS (kuri)) ya MOSFET ni bike, bifasha kugabanya gukoresha amashanyarazi. Na none, muburyo bwo guhagarika, gukoresha ingufu za static ni bike cyane kuko irembo ryinjira hafi ya zeru.

Muri make, MOSFETs yitwa ibikoresho bigenzurwa na voltage kuko ihame ryimikorere ryayo rishingiye cyane cyane kugenzura imiyoboro y'amazi na voltage yumuryango. Ibi bigenzurwa na voltage biranga bituma MOSFETs isezeranya ibintu byinshi muburyo bwa elegitoroniki, cyane cyane aho inzitizi nyinshi zinjira, urusaku ruke, umuvuduko wihuse hamwe no gukoresha ingufu nke.
