Iimpawu conduction MOSFET

I-MOSFET conductivity ithetha ukuba isetyenziswe njengotshintshi, olulingana nokuvalwa kokutshintsha.I-NMOS ibonakaliswe njengokuqhuba xa i-Vgs idlula ixabiso elilinganiselweyo, elisebenza kwimeko kunye nomthombo oqhagamshelwe kwisixhobo esisekelwe phantsi, kwaye ifuna kuphela isango. amandla ombane abe yi-4V okanye i-10V.I-PMOS, ngakolunye uhlangothi, iqhuba xa i-Vgs iwela ngaphantsi kwexabiso elithile, kwaye ifanelekile kwiimeko apho umthombo uxhunywe kwiVcc. Nangona kunjalo, nangona i-PMOS inokufaneleka njengomqhubi womgangatho ophezulu, i-NMOS isetyenziswa ngokubanzi kubaqhubi abakwibakala eliphezulu ngenxa yokumelana okukhulu, ixabiso eliphezulu kunye neendleko, kunye neentlobo ezimbalwa zokutshintshwa.

Nokuba kunjaloNMOSokanye i-PMOS, kuya kubakho ukuchasana emva kokuchasana, ukwenzela ukuba i-current in the resistance ukuba idle isixa esithile samandla, oku kusetyenziswa kubizwa ngokuba yi-resistance loss. Okwangoku, sikhetha ukuxhathisa kwe-MOSFET encinci kunokunciphisa ilahleko yokuxhathisa, amandla aphantsi namhlanje.I-MOSFETon-resistance ngokubanzi ziimiliyohm ezininzi, okanye iimiliyohm ezimbalwa zenkangeleko yeMOS kwimeko yokuqhubeka nanjengoko kugqitywe imeko ayikho ngephanyazo.
Amandla ombane kumacala omabini e-MOS anenkqubo yokuncipha, ekhoyo ngoku equkuqelayo kwinkqubo yokwanda, ngeli xesha lexesha, amandla ombane kunye nangoku aphindaphindwe ngobungakanani bokulahleka kweMOSFET. Ilahleko yokutshintsha ngokubanzi inkulu kakhulu kunokulahleka kokuqhuba, kwaye ukuba iphezulu isantya sokutshintsha, kokukhona ilahleko inkulu. Ukuphakama kokuphindaphinda kwamandla ombane kunye nangoku ngexesha lokuqhuba, ilahleko ephezulu. Ukuba sinokunciphisa ixesha lokutshintsha, sinokunciphisa ilahleko kwi-conduction nganye, ukunciphisa ukuphindaphinda kokutshintsha, kwakhona kunokunciphisa ukuphindaphinda kokutshintsha ngaphakathi kwexesha elithile, ukuze kuncitshiswe ilahleko yokutshintsha.

Ngophuhliso olusebenzayo lwemarike kunye nokuhlanganiswa kobutyebi okusebenzayo, olukey ibe yenye yezona arhente zibalaseleyo nezikhula ngokukhawuleza e-Asia, kwaye yinjongo eqhelekileyo ka olukey ukuba yeyona arhente ixabisekileyo ehlabathini. Ukutyhubela iminyaka, inkampani olukey ukusinda ngetyala, ukubambelela "umgangatho kuqala, inkonzo kuqala" injongo kunye namashishini amaninzi asekhaya kunye namazwe angaphandle zobugcisa, imveliso yokuqala ukuseka ubudlelwane obuhle ukusebenza, kunye neminyaka emininzi yamava yobungcali ekusasazeni, ngetyala elilungileyo, inkonzo ebalaseleyo, kwaye wafumana intembeko nenkxaso ngokubanzi.
