Inshingano eshatu zingenzi za MOSFETs

MOSFET isanzwe ikoreshwa mubikorwa bitatu byingenzi ni imiyoboro ya amplification, guhora isohoka no guhinduranya.

 

1, umuzunguruko

MOSFET ifite impedance nyinshi yinjiza, urusaku ruke nibindi biranga, kubwibyo, mubisanzwe ikoreshwa nkibyiciro byinshi byongera ibyiciro byinjira byubu, kimwe na transistor, ukurikije ibyinjira nibisohoka byumuzingo rusange wihitamo zinyuranye, zishobora kugabanywamo leta eshatu zumuzunguruko waBYINSHI, kimwe, isoko rusange, kumeneka rusange hamwe n irembo rusange. Igishushanyo gikurikira cyerekana MOSFET isanzwe ikwirakwizwa ryumuzunguruko, aho Rg arwanya irembo, igabanuka rya voltage ryongewe kumuryango; Rd niyirwanya imiyoboro, imiyoboro yamazi ihindurwamo umuyaga wamazi, bigira ingaruka kumagambo ya amplification Au; Amafaranga niyo arwanya isoko, atanga kubogama kubogamye kumuryango; C3 ni capacitor ya bypass, ikuraho attenuation yikimenyetso cya AC kumafaranga.

 

 

2, isoko ya none

Inkomoko ihoraho ikoreshwa cyane mugupima metrologiya, nkuko bigaragara ku gishushanyo gikurikira, igizwe ahaniniBYINSHIburigihe isoko yumuzunguruko, irashobora gukoreshwa nka magneto-amashanyarazi ya metero yo gupima igipimo. Kubera ko MOSFET ari igikoresho cyo kugenzura ubwoko bwa voltage, irembo ryacyo hafi ya ntirifata ibyagezweho, impedance yinjira ni ndende cyane. Niba ikintu kinini gihoraho gisohoka cyifuzwa kunonosora ukuri, guhuza inkomoko yo kugereranya no kugereranya birashobora gukoreshwa kugirango ubone ingaruka zifuzwa.

 

3, guhinduranya

Uruhare rwingenzi rwa MOSFET ninshingano yo guhinduranya. Guhindura, ibyinshi muburyo butandukanye bwo kugenzura imitwaro ya elegitoronike, guhinduranya amashanyarazi, nibindi byingenzi biranga umuyoboro wa MOS ni uguhindura ibintu byiza, kuriNMOS. Kuri PMOS, kurundi ruhande, Vgs munsi yagaciro runaka izakora, ikoreshwa murubanza iyo isoko ishingiye kuri VCC, ni ukuvuga, disiki yanyuma. Nubwo PMOS ishobora gukoreshwa byoroshye nkumushoferi wohejuru, NMOS mubusanzwe ikoreshwa mubashoferi bo murwego rwo hejuru bitewe no guhangana cyane, igiciro kinini, nubwoko buke bwo gusimbuza.

 

Usibye inshingano eshatu zingenzi zavuzwe haruguru, MOSFETs irashobora kandi gukoreshwa nkurwanya ruhindagurika kugirango tumenye imbaraga ziyobowe na voltage, kandi ifite na progaramu nyinshi.
