Reba kuri MOSFETS

MOSFETs irinda MOSFETs mumuzunguruko uhuriweho.MOSFETS, nkimwe mubikoresho byibanze muriigice cya kabiri umurima, bikoreshwa cyane mubuyobozi-urwego rwumuzunguruko kimwe no muburyo bwa IC.Imiyoboro nisoko yaMOSFETS Birashobora guhinduranya, kandi bigakorwa muburyo bwa P bwinyuma hamwe nakarere ka N. Muri rusange, amasoko yombi arashobora guhinduranya, byombi bigize N-bwoko bwakarere muriP-inyuma yinyuma. Muri rusange, utwo turere twombi turasa, kandi niyo ibyo bice byombi byahinduwe, imikorere yigikoresho ntabwo izagira ingaruka. Kubwibyo, igikoresho gifatwa nkikigereranyo.

Ihame:

MOSFET ikoresha VGS kugirango igenzure umubare w "amafaranga yishyuwe" kugirango ihindure imiterere yumuyoboro wogukora wakozwe naya "yishyurwa" kugirango ugenzure imiyoboro y'amazi. Iyo MOSFETs ikozwe, umubare munini wa ion nziza igaragara murwego rwimikorere ikoresheje inzira zidasanzwe, kugirango ibicuruzwa byinshi bibi bishobora kumvikana kurundi ruhande rwimbere, kandi N-karere k’imyanda ihumanya cyane ihujwe na ibi byishyurwa bibi, kandi umuyoboro uyobora urakorwa, hamwe numuyoboro munini ugereranije, ID, ubyara nubwo VGS ari 0. Niba voltage yumuryango ihinduwe, umubare wamafaranga yatanzwe mumurongo nayo arahinduka, nubugari y'umuyoboro uyobora uhinduka kurwego rumwe. Niba voltage yumuryango ihindutse, umubare wamafaranga yatanzwe mumurongo nayo azahinduka, kandi ubugari mumuyoboro uyobora nabyo bizahinduka, bityo indangamuntu yumuyoboro izahinduka hamwe na voltage yumuryango.

Uruhare:

1. Irashobora gukoreshwa kumuzunguruko. Kubera kwinjiza kwinshi kwinshi kwa amplifier ya MOSFET, ubushobozi bwo guhuza bushobora kuba buto kandi ubushobozi bwa electrolytike ntibushobora gukoreshwa.

Kwinjira kwinshi kwingirakamaro birakwiriye guhinduka. Bikunze gukoreshwa muguhindura impedance murwego rwo kwinjiza ibyiciro byinshi byongera imbaraga.

3 can Irashobora gukoreshwa nka résistoriste ihinduka.

4, irashobora gukoreshwa nka enterineti.

MOSFETs ubu ikoreshwa muburyo butandukanye bwa porogaramu, harimo imitwe yumurongo mwinshi muri tereviziyo no guhinduranya amashanyarazi. Muri iki gihe, bipolar transistors isanzwe hamwe na MOS byahujwe hamwe kugirango bibe IGBT (inzugi zifunguye bipolar transistor), ikoreshwa cyane ahantu hafite ingufu nyinshi, kandi imiyoboro ihuriweho na MOS ifite ibiranga gukoresha ingufu nke, none CPU yakoreshejwe cyane muri Inzira nyinshi.
