Uhlalutyo lweParameter kunye nomlinganiselo weMOSFETs

Kukho iintlobo ezininzi zeeparamitha eziphambili zeI-MOSFET, equlathe i-DC yangoku, iiparamitha zangoku ze-AC kunye neeparamitha zomda, kodwa isicelo ngokubanzi sidinga kuphela ukukhathalela ezi parameters ezisisiseko zilandelayo: imeko yokuzaliseka komthombo wokuvuza yangoku ye-IDSS pinch-off voltage Up, transconductance gm, ukuvuza komthombo wokuqhekeka kombane weBUDS, ilahleko enkulu yemveliso yamandla ePDSM kunye nomthombo omkhulu wokuvuza weIDSM yangoku.

1.Umthombo wokuvuza ogcweleyo okwangoku

I-IDSS yangoku yomthombo we-drain-source yangoku ithetha i-drain-source current kumbane wesango i-UGS = 0 ekudibaneni okanye ukuncipha kohlobo lwesango eligqunyiweyo lomaleko we-MOSFETs.

2. I-Clip-off voltage

I-pinch-off yamandla ombane i-UP ithetha amandla ombane esango asebenzayo kwisiphambuka okanye uhlobo lokuncipha lwesango lomaleko olugqunyiweyoI-MOSFEToko kwenza idrain-source inqunyulwe nje. Khangela ukuba i-IDSS kunye ne-UP zithetha ukuthini.

3, Vula amandla ombane

Umbane wokuvula i-UT uthetha amandla ombane esango asebenzayo kwisango eligqunyiweyo le-MOSFET ukuze umdibaniso womthombo wokuhambisa amanzi uvulelwe nje. Khangela ukuba i-UT ithetha ukuthini.

4.Isikhokelo esinqamlezileyo

I-transguide gm isetyenziselwa ukubonisa amandla ombane womthombo wesango ukulawula i-drain current, oko kukuthi, umlinganiselo phakathi kokutshintshwa kwe-drain current kunye nokutshintsha kombane womthombo wesango.

5, Ubuninzi belahleko yemveliso yamandlar

Ubuninzi belahleko yemveliso yamandla nawo akwi parameter elinganiselweyo, nto leyo ethetha ukuba awona mandla aphezulu elahleko yomthombo wedreyini anokuvunyelwa xa kusenziwa umbane.I-MOSFETiqhelekile kwaye ayichaphazeleki. Xa sisebenzisa i-MOSFET, ukulahleka kwayo komsebenzi kufuneka kube ngaphantsi kwePDSM kunye nexabiso elithile.

6, Ubuninzi bokuvuza komthombo wangoku

Owona mthombo uphezulu we-drain-source current, i-IDSM, ikwasisithintelo sepharamitha, nto leyo ethetha owona mbane uphezulu uvumelekileyo ukuba udlule phakathi komsele kunye nomthombo we-MOSFET ngexesha lomsebenzi wesiqhelo, kwaye akufuneki ugqithwe xa iMOSFET isebenza.

olukey ibe yenye yezona arhente zibalaseleyo nezikhula ngokukhawuleza eAsia ngophuhliso lwemarike olusebenzayo kunye nohlanganiso olusebenzayo lwezixhobo, kwaye ukuba yeyona arhente ixabisekileyo kwihlabathi yinjongo efanayo yolukey.
