Nei MOSFETs voltage ichidzorwa?

MOSFETs (Metal Oxide Semiconductor Field Effect Transistors) anonzi magetsi anodzorwa midziyo kunyanya nekuti mashandiro awo anonyanya kutsamira pakutonga kwegedhi voltage (Vgs) pamusoro pekudonhedza ikozvino (Id), pane kuvimba neyazvino kuti idzore, se. ndizvo zvakaita bipolar transistors (seBJTs). Iyi inotevera tsananguro yakadzama yeMOSFET sechinhu chinodzorwa nemagetsi:

Kushanda Nheyo

Gedhi Voltage Control:Mwoyo weMOSFET uri muchimiro chiri pakati pegedhi rayo, sosi uye dhizaini, uye insulating layer (kazhinji silicon dioxide) pasi pegedhi. Kana magetsi akaiswa kugedhi, munda wemagetsi unogadzirwa pasi pechidzitiro chekudzivirira, uye munda uyu unoshandura conductivity yenzvimbo pakati pechitubu nekudonha.

Conductive Channel Formation:Kune N-channel MOSFETs, kana gedhi remagetsi Vgs rakakwira zvakakwana (pamusoro pemutengo chaiwo unonzi threshold voltage Vt), maerekitironi ari muP-type substrate pazasi pegedhi anokwezvwa nechepasi peiyo insulating layer, achigadzira N- mhando conductive chiteshi inobvumira conductivity pakati pechitubu uye dhizaini. Sezvineiwo, kana Vgs yakaderera pane Vt, chiteshi chekufambisa hachina kuumbwa uye MOSFET iri padanho.

Drain current control:saizi yekudonhedza ikozvino Id inonyanya kudzorwa negedhi voltage Vgs. Iyo yakakwirira iyo Vgs, iyo yakafara nzira yekuitisa inoumbwa, uye yakakura iyo yekudonha ikozvino Id. Hukama uhwu hunobvumira iyo MOSFET kuti iite semagetsi anodzorwa ikozvino mudziyo.

Piezo Characterization Advantages

High Input Impedance:Iyo yekupinza impedance yeMOSFET yakakwira zvakanyanya nekuda kwekuparadzaniswa kwegedhi uye sosi-yekudonhedza dunhu neinodzivirira layer, uye gedhi razvino rinenge razero, izvo zvinoita kuti ive yakakosha mumaseketi panodiwa yakakwira yekupinza impedance.

Noise Yakaderera:MOSFETs inogadzira ruzha rwakaderera panguva yekushanda, zvakanyanya nekuda kweiyo yakakwira yekupinza impedance uye unipolar carrier conduction maitiro.

Fast switching speed:Sezvo maMOSFET ari midziyo inodzorwa nevoltage, kumhanya kwavo kwekuchinja kunowanzo kukurumidza kupfuura kuya kwebipolar transistors, iyo inofanirwa kupinda muhurongwa hwekuchaja kuchengetedza uye kuburitswa panguva yekuchinja.

Kushandisa Simba Kwakaderera:Munyika, iyo drain-source kuramba (RDS(on)) yeMOSFET yakadzikira, iyo inobatsira kudzikisa simba rekushandisa. Zvakare, mune cutoff state, iyo static simba rekushandisa yakadzikira nekuti gedhi razvino rinenge zero.

Muchidimbu, maMOSFET anodaidzwa kunzi voltage-inodzorwa midziyo nekuti yavo yekushandisa inotsamira zvakanyanya pakudzora kweiyo drain ikozvino negedhi voltage. Izvi zvinodzorwa nevoltage hunhu hunoita kuti MOSFETs ivimbise kune dzakasiyana siyana mashandisirwo mumaseketi emagetsi, kunyanya panodiwa kukwirisa kupinza, ruzha rwakadzika, kukurumidza kushandura uye kuderera kwesimba rekushandisa.
