Sida loo go'aamiyo MOSFET-ta awoodda sare leh waxay ku gubtay gubashada

(1) MOSFET waa curiye wax-is-beddela, halka transistor-ku uu yahay curiye wax-is-beddelaya. Awoodda wadista lama heli karo, hadda waduhu aad buu u yar yahay, waa in la doortaaMOSFET; iyo in danab signal waa yar yahay, oo ballan qaaday in ay ka qaadan wax badan hadda ka mashiinka kalluumaysiga korontada xaaladaha marxaladda, waa in la doorto transistor.

 

(2) MOSFET waa isticmaalka badiyaa sidayaal kombuyuutar ah, oo loogu yeero aaladda unipolar, halka transistor-ku uu yahay in ay jiraan inta badan sidayaal, laakiin sidoo kale isticmaalka tiro yar oo xambaaro sidayaal ah. Waxaa loo yaqaanaa aaladda laba-cirifoodka.

 

(3) QaarMOSFET isha iyo bulaacada waxaa lagu beddelan karaa isticmaalka danab albaabka waxay noqon kartaa mid togan ama taban, dabacsanaan ka badan transistor waa wanaagsan yahay.

 

(4) MOSFET waxay ku shaqayn kartaa xaalad aad u yar oo hadda jirta oo aad u yar, hanaankeeda wax-soo-saarku wuxuu noqon karaa mid aad ugu habboon in lagu dhex daro MOSFETs badan oo ku jira chip silikon, sidaas darteed MOSFET-yada wareegyada isku dhafan ee baaxadda weyn ayaa si weyn loo isticmaalay.

 

(5) MOSFET waxay leedahay faa'iidooyinka is-hortaagga sare ee wax-soo-saarka iyo buuqa hooseeya, sidaas darteed waxaa sidoo kale si ballaaran loogu adeegsadaa qalabyada dabinka elektaroonigga ah ee kala duwan. Gaar ahaan tuubada saamaynta goobta si ay u sameeyaan gelinta qalabka elektarooniga oo dhan, heerka wax soo saarka, waxay heli kartaa transistor-ka guud way adagtahay in la gaaro shaqada.

 

(6)MOSFETs waxay u qaybsantaa laba qaybood: nooca isgoysyada cas iyo nooca albaabka dahaarka ah, iyo mabaadi'dooda wax-is-dabamarinta waa isku mid.

 

Dhab ahaantii, triode waa ka jaban yahay oo ku habboon in la isticmaalo, sida caadiga ah loo isticmaalo kalluumaysatadii hore ee hooseeya, MOSFET ee wareegyada xawaaraha sare ee xawaaraha sare, marxaladaha hadda jira, sidaas darteed nooca cusub ee kalluumaysatada ultrasonic-soo noqnoqda sare, lagama maarmaanka ah. waa kaMOS weyn. guud ahaan marka la hadlo, munaasabadaha qiimaha jaban, isticmaalka guud ee marka hore si loo tixgeliyo isticmaalka transistor-ka, maaha haddii aad rabto inaad tixgeliso MOS.

 

MOSFET waa sababaha burburay xalalkuna waa sida soo socota

 

Marka hore, caabbinta wax soo saarka MOSFET lafteedu waa mid aad u sareysa, iyo albaabka - isha isha inter-electrode capacitance waa mid aad u yar, sidaas darteed aad bay u nuglaadaan meelaha korantada dibadda ama electrostatic inductance oo lagu dallaco, iyo qadar yar oo lacag ah ayaa la samayn karaa. ee awoodda inter-electrode ee tamarta sare ee ku habboon (U = Q / C), waxay dhaawacmi doontaa tuubada. In kasta oo gelinta MOS ee mashiinka kalluumeysiga koronto uu leeyahay cabbirro dayactirka-iska-hortagga ah, laakiin weli waxay u baahan tahay in si taxaddar leh loogu daweeyo, kaydinta iyo gaarsiinta weelasha birta ee ugu fiican ama baakadaha qalabka korantada, ha gelin si fudud si aad u weerarto danab sarreeya. walxaha kiimikaad ama ka samaysan fiber kiimikaad. Isku soo wada duuboo, hawlgelinta, walxaha, muuqaalka, goobta shaqada, iwm. waa in ay noqdaan kuwo si heersare ah loo soo dhisay. Si looga fogaado waxyeelada faragelinta korantada ee hawlwadeenka, sida waa in aan la xidhin naylon, dharka kiimikaad fiber-ka, gacanta ama shay ka hor inta aanad taaban qaybta isku dhafan ayaa ugu fiican in la isku xidho dhulka. Qalabku hagayo toosinta iyo leexinta ama alxanka gacanta, isticmaalka qalabku waxa uu lagama maarmaan u yahay dejinta heersare ah.
