PMOSFET ni iki, urabizi?

I. Imiterere shingiro nihame ryakazi

1. Imiterere shingiro

PMOSFETs ifite n-insimburangingo na p-imiyoboro, kandi imiterere yabyo igizwe ahanini n irembo (G), isoko (S) numuyoboro (D). Kuri n-ubwoko bwa silicon substrate, hari uturere tubiri twa P + dukora nkisoko namazi, kandi, bihuzwa hagati yabyo p-umuyoboro. Irembo riherereye hejuru yumuyoboro kandi ritandukanijwe numuyoboro nicyuma cya oxyde yicyuma.

2. Amahame yimikorere

PMOSFETs ikora kimwe na NMOSFETs, ariko hamwe nubwoko butandukanye bwabatwara. Muri PMOSFET, abatwara nyamukuru ni ibyobo. Iyo voltage itari nziza ishyizwe kumuryango kubijyanye ninkomoko, p-ubwoko bwa p-inverse igizwe hejuru yubuso bwa n-bwoko bwa silicon munsi y irembo, bukora nk'umuyoboro uhuza isoko n'amazi. Guhindura amarembo yumuriro uhindura ubwinshi bwimyobo mumuyoboro, bityo ukagenzura imiyoboro yumurongo. Iyo voltage yumuryango ari muke bihagije, ubwinshi bwimyobo mumuyoboro bugera murwego rwo hejuru bihagije kugirango yemere gutwarwa hagati yisoko n'amazi; muburyo bunyuranye, umuyoboro urahagarara.

II. Ibiranga nibisabwa

1. Ibiranga

Umuvuduko muke: P-umuyoboro wa MOS tristoriste ifite umuvuduko muke ugereranije, bityo transconductance ya transistors ya PMOS ni ntoya ugereranije na transistor ya NMOS munsi ya geometrie imwe na voltage ikora.

Bikwiranye numuvuduko muke, porogaramu nkeya: Bitewe nubushobozi buke, PMOS ihuriweho hamwe irakenewe cyane mubisabwa mu muvuduko muke, ahantu hake cyane.

Imiterere yimyitwarire: Imiterere yimyitwarire ya PMOSFETs itandukanye na NMOSFETs, bisaba voltage yumuryango munsi yumuriro wa voltage.

1. Porogaramu

Guhindura uruhande rwo hejuru: PMOSFETs isanzwe ikoreshwa muburyo bwo guhinduranya ibice byo hejuru aho isoko ihujwe no gutanga ibintu byiza kandi imiyoboro ihujwe nimpera nziza yumutwaro. Iyo PMOSFET ikora, ihuza impera nziza yumutwaro kubintu byiza, bigatuma amashanyarazi atembera mumuzigo. Iboneza nibisanzwe mubice nko gucunga ingufu na moteri ya moteri.

Inzitizi zo Kurinda Inyuma: PMOSFETs irashobora kandi gukoreshwa mukuzunguruka gukingira kugirango hirindwe kwangirika kwumuzunguruko uterwa no gutanga amashanyarazi cyangwa kugarukira inyuma.

III. Gutegura no gutekereza

1. KUGENZURA AMATORA

Mugihe utegura imirongo ya PMOSFET, kugenzura neza voltage yumuryango birasabwa kugirango ukore neza. Kubera ko imiterere ya PMOSFETs itandukanye niyya NMOSFETs, hagomba kwitabwaho polarite nubunini bwa voltage yumuryango.

2. Guhuza imizigo

Iyo uhuza umutwaro, hagomba kwitonderwa polarite yumutwaro kugirango harebwe neza ko ikigezweho neza binyuze muri PMOSFET, ningaruka zumutwaro kumikorere ya PMOSFET, nko kugabanuka kwa voltage, gukoresha ingufu, nibindi. , na none bigomba gusuzumwa.

3. Guhagarara k'ubushyuhe

Imikorere ya PMOSFETs yibasiwe cyane nubushyuhe, bityo rero ingaruka zubushyuhe ku mikorere ya PMOSFETs zigomba kwitabwaho mugihe cyo gutegura imirongo, kandi hagomba gufatwa ingamba zijyanye no kuzamura ubushyuhe bwumuzunguruko.

4. Inzira zo gukingira

Kugirango wirinde PMOSFETs kwangizwa n’umuvuduko ukabije n’umuvuduko ukabije mu gihe cyo gukora, hagomba gushyirwaho imiyoboro yo gukingira nko gukabya gukingira no gukabya ingufu zikabije. Izi nzitizi zo kurinda zirashobora kurinda neza PMOSFET no kongera ubuzima bwa serivisi.

Muri make, PMOSFET ni ubwoko bwa MOSFET ifite imiterere yihariye nihame ryakazi. Kugenda kwayo kwinshi kandi bikwiranye n'umuvuduko muke, progaramu-nke ya progaramu ituma ikoreshwa cyane mubice byihariye. Mugihe utegura imiyoboro ya PMOSFET, hagomba kwitonderwa kugenzura irembo rya voltage, guhuza imizigo, guhagarara kwubushyuhe no kurinda umutekano kugirango ukore neza kandi byizewe byumuzunguruko.
