Kusanthula kwa parameter ndi kuyeza kwa MOSFETs

Pali mitundu yambiri yamagawo akuluakulu aMOSFET, yomwe ili ndi ma DC apano, magawo apano a AC ndi malire, koma kugwiritsa ntchito pafupipafupi kumangofunika kusamala magawo oyambira awa: machulukitsidwe a gwero lotayikira pano IDSS kutsina voteji Up, transconductance gm, kutayikira gwero lamagetsi BUDS, Kutayika kwakukulu kwa mphamvu ya PDSM ndi gwero lalikulu la IDSM lamakono.

1.Saturated kutayikira gwero panopa

IDSS yodzaza ndi gwero lapano la IDSS imatanthawuza kukhetsa komwe kumachokera pamagetsi a chipata UGS = 0 pamphambano kapena mtundu wocheperako wa chipata cha MOSFET.

2. Chotsitsa chamagetsi

Pinch-off voltage UP imatanthawuza mphamvu yamagetsi ogwiritsira ntchito pachipata pamphambano kapena mtundu wa depletion wosanjikiza chipata.MOSFETzomwe zimapangitsa kuti drain-source iwonongeke. Dziwani zomwe IDSS ndi UP zimatanthauza.

3, Yatsani magetsi

Mphamvu yamagetsi ya UT imatanthawuza mphamvu yamagetsi ogwiritsira ntchito pachipata mu MOSFET yolumikizidwa ndi chipata kuti cholumikizira cholumikizira chitseko chiziyatsidwa. Dziwani zomwe UT ikutanthauza.

4.Malangizo odutsa

Transguide gm imagwiritsidwa ntchito kuwonetsa kuthekera kwa chipata gwero lamagetsi kuwongolera kukhetsa kwapano, ndiye kuti, chiŵerengero chapakati pa kusintha kwa kukhetsa kwapano ndi kusintha kwa magetsi a chipata.

5, Kutaya kwakukulu kwa mphamvu zotulutsar

Mphamvu yotulutsa yotayika kwambiri imakhalanso ya malire, zomwe zikutanthauza kuti mphamvu yotayika kwambiri yotayika yomwe imatha kuloledwa ikamagwira ntchito.MOSFETndi zabwinobwino komanso zosakhudzidwa. Tikamagwiritsa ntchito MOSFET, kutayika kwake kuyenera kukhala kotsika kuposa PDSM ndi mtengo wina.

6, Maximum kutayikira gwero panopa

The maximum drain-source current, IDSM, imakhalanso yochepetsera malire, kutanthauza kuti pakali pano amaloledwa kudutsa pakati pa kukhetsa ndi gwero la MOSFET panthawi ya ntchito yabwino, ndipo sayenera kupitirira pamene MOSFET ikugwira ntchito.

olukey wakhala m'modzi mwa othandizira omwe akukula mwachangu ku Asia kudzera mukutukuka kwa msika komanso kuphatikiza kothandiza kwa zinthu, ndipo kukhala wothandizira wofunika kwambiri padziko lonse lapansi ndicho cholinga chofala cha olukey.
