U fiirso MOSFETs

MOSFET-yadu waxay ku dahaadhaan MOSFET-yada wareegyada isku dhafan. MOSFETs, oo ah mid ka mid ah aaladaha aasaasiga ahsemiconductor garoonka, waxaa si weyn loo isticmaalaa in wareegyada heerka guddiga iyo sidoo kale in design.The IC design.The bullaacadaha iyo ishaMOSFET-yada waa la isweydaarsan karaa, waxaana lagu sameeyay albaab dambe oo nooca P ah oo leh gobol N-nooca ah. Guud ahaan, labada ilood waa la isweydaarsan karaa, labaduba waxay ka samaysan yihiin gobolka N-noocaGadaasha dambe ee nooca P. Guud ahaan, labadan aag waa isku mid, xitaa haddii labadan qaybood la beddelo, ma saameyn doonto waxqabadka qalabka. Sidaa darteed, qalabka waxaa loo tixgeliyaa inuu yahay mid siman.

Mabda'a:

MOSFET waxay isticmaashaa VGS si ay u xakamayso qadarka "lacag la kiciyey" si ay u bedesho xaalada kanaalka korantada ee ay sameeyeen "kharashyada la kiciyey" si loo xakameeyo qulqulka qulqulka hadda. Marka MOSFET-yada la soo saaro, tiro badan oo ion togan ayaa ka muuqda lakabka dahaadhka iyada oo loo marayo habab gaar ah, si kharashyo badan oo taban loo dareemo dhinaca kale ee interface-ka, iyo N-gobolka ee wasakhda sare-sare waxaa ku xiran Kharashyadan taban, iyo kanaalka korantada ayaa la sameeyay, iyo qulqulka qulqulaya, ID, ayaa la soo saaray xitaa haddii VGS uu yahay 0. Haddii korontada albaabka la beddelo, qadarka lacagta la kiciyay ee kanaalka ayaa sidoo kale isbeddelaya, iyo ballaca ee channel conductive isbedel isku mid ah. Haddii korantada albaabka isbeddesho, qadarka kharashka la kiciyay ee kanaalka ayaa sidoo kale isbeddeli doona, iyo ballaca kanaalka wax qabanaya ayaa sidoo kale isbeddeli doona, markaa aqoonsiga hadda jira ayaa isbeddeli doona iyadoo ay weheliso danabka albaabka.

Doorka:

1. Waxaa lagu dabaqi karaa wareegga cod-weyneyaasha. Sababtoo ah cilad-gelinta sare ee cod-weyneeye MOSFET, awoodda isku-xidhka ayaa noqon karta mid yar oo korantada korantada lama isticmaali karo.

Cilad-gelinta sare waxay ku habboon tahay beddelka impedance. Waxaa inta badan loo isticmaalaa beddelka impedance ee marxaladda gelinta ee amplifiers heerar badan.

3. Waxaa loo isticmaali karaa sida resistor variable.

4, waxaa loo isticmaali karaa sidii qalab elektaroonik ah.

MOSFET-yada waxaa hadda loo isticmaalaa codsiyo kala duwan oo kala duwan, oo ay ku jiraan madax-noocyo badan oo telefishinnada ah iyo beddelidda sahayda korontada. Maalmahan, laba-barnaamijiyeyaasha caadiga ah ee laba-cirifoodka ah iyo MOS ayaa la isku daray si ay u sameeyaan IGBT (transistor gate bipolar transistor), kaas oo si weyn looga isticmaalo meelaha awoodda sare leh, iyo MOS isku-dhafka ah ayaa leh dabeecadda isticmaalka tamarta hoose, hadda CPU-yada ayaa si ballaaran loo isticmaalay Wareegyada MOS.
