Kumenyekanisha Irembo Ryubatswe MOSFETS

Irembo ryurugero rwubwoko bwanditse MOSFET aliasBYINSHI .

MOSFET nayoUmuyoboro na P-umuyoboro ibyiciro bibiri, ariko buri cyiciro kigabanijwe mukuzamura no kugabanuka k'ubwoko bwa kabiri, bityo hariho ubwoko bune:Kuzamura umuyoboro, Umuyoboro wa P-umuyoboro, N-umuyoboro wumucyo, Ubwoko bwa P-umucyo. Ariko aho amarembo yinkomoko yumuriro ari zeru, imiyoboro yamazi nayo ni zeru yumuyoboro wongerewe umuyoboro. Nyamara, aho amarembo yinkomoko yumuriro ari zeru, umuyoboro wamazi ntabwo ari zeru ushyirwa mubikorwa nkibikoresho bitwara urumuri.
Ihame rya MOSFET yazamuye:

Iyo ukorera hagati yinkomoko y amarembo ntabwo ukoresha voltage, hagati yisoko yamazi PN ihuza iba muburyo bunyuranye, ntihazabaho umuyoboro uyobora, kabone niyo hagati yisoko y'amazi hamwe na voltage, the umuyoboro wogutwara amashanyarazi urafunzwe, ntibishoboka kugira umuyoboro wakazi ukurikije. Iyo hagati yinkomoko y irembo hiyongereyeho icyerekezo cyiza cyumubyigano kugiciro runaka, hagati yisoko yamazi bizatanga umuyoboro wumutekano utwara, kuburyo umwobo wogutwara umaze gukorwa niri soko ryamashanyarazi witwa voltage bita VGS ifunguye, nini hagati y irembo ryamasoko ya voltage, umwobo uyobora ni mugari, ari nako bituma unyura mumashanyarazi menshi.

Ihame ryumucyo utandukanya MOSFET:

Mubikorwa, nta voltage ikoreshwa hagati yinkomoko y irembo, bitandukanye nubwoko bwiyongera bwa MOSFET, kandi umuyoboro uyobora ubaho hagati yisoko y'amazi, bityo rero voltage nziza yonyine yongewe hagati yisoko y'amazi, ayo ibisubizo mumazi atemba. Byongeye kandi, isoko y amarembo hagati yicyerekezo cyiza cya voltage, kwagura umuyoboro wogukwirakwiza, ongeraho icyerekezo gitandukanye cya voltage, umuyoboro uyobora uragabanuka, binyuze mumashanyarazi azaba mato, hamwe no kongera kugereranya MOSFET, irashobora kandi kuba mumibare myiza kandi itari myiza yumubare runaka wuturere murwego rwumuyoboro.

MOSFET ikora neza:

Ubwa mbere, MOSFETs zikoreshwa mugukuza. Kuberako ibyinjira byinjira muri MOSFET amplifier ari ndende cyane, kubwibyo filteri ya filteri irashobora kuba nto, bitabaye ngombwa ko ikoresha amashanyarazi.

Icya kabiri, MOSFET irwanya cyane iyinjiza irakwiriye cyane cyane kubiranga impedance ihinduka. Mubisanzwe bikoreshwa murwego rwinshi rwongera amplifier ibyiciro kugirango biranga impedance ihinduka.

MOSFET irashobora gukoreshwa nkibishobora guhinduka.

Icya kane, MOSFET irashobora koroha nkumuriro wa DC.

V. MOSFET irashobora gukoreshwa nkibintu byo guhinduranya.
