Maitiro ekuona nMOSFETs uye pMOSFETs

I. Maererano negwara rekuyerera kwezvino

NMOSFET:Kana yazvino ichiyerera ichibva kutsime (S) kuenda kudhiramu (D), iyo MOSFET iNMOSFET MuNMOSFET, kwainobuda uye kudonhedza ndeye n-mhando semiconductors uye gedhi iri p-mhando semiconductor. Kana magetsi egedhi ari akanaka maererano nekwakabva, n-type conducting channel inoumbwa pamusoro pe semiconductor, ichibvumira maerekitironi kuyerera kubva kutsime kuenda kumvura.

PMOSFET:MOSFET iPMOSFET kana yazvino ichiyerera ichibva kudhiraini (D) ichienda kutsime (S) MuPMOSFET, zvese kwainobva uye kudonhedza ari p-mhando semiconductors uye gedhi iri n-mhando semiconductor. Kana magetsi egedhi asina kunaka maererano nekwakabva, p-type conducting channel inoumbwa pamusoro pe semiconductor, ichibvumira maburi kuyerera kubva kutsime kuenda kumvura (ona kuti mutsanangudzo yemazuva ose tichiri kutaura kuti ikozvino. inoenda kubva kuD kuenda kuS, asi ndiyo nzira inoenda nemakomba).

II. Maererano neparasitic diode direction

NMOSFET:Kana iyo parasitic diode inongedza kubva kunobva (S) kudonhedza (D), iNMOSFET. parasitic diode chimiro chemukati mukati meMOSFET, uye kutungamira kwayo kunogona kutibatsira kuona rudzi rweMOSFET.

PMOSFET:Iyo parasitic diode ndeye PMOSFET painonongedza kubva pakudonhedza (D) kuenda kunobva (S).

III. Maererano nehukama pakati pekutonga electrode voltage uye magetsi conductivity

NMOSFET:Iyo NMOSFET inoitisa kana gedhi voltage iri yakanaka maererano neiyo sosi voltage. Izvi zvinodaro nekuti yakanaka gedhi voltage inogadzira n-mhando yekuitisa nzira pane semiconductor pamusoro, ichibvumira maerekitironi kuyerera.

PMOSFET:A PMOSFET inoitisa kana gedhi voltage isina kunaka maererano neiyo sosi voltage. A negative gedhi voltage inogadzira p-mhando inoitisa chiteshi pane semiconductor pamusoro, ichibvumira maburi kuyerera (kana ikozvino kuyerera kubva kuD kuenda kuS).

IV. Dzimwe nzira dzekubatsira dzekutonga

Ona zviratidzo zvemudziyo:Pane mamwe maMOSFET, panogona kunge paine yekumaka kana nhamba yemuenzaniso inoratidza rudzi rwayo, uye nekubvunza dhatabheti rakakodzera, unogona kusimbisa kana iri NMOSFET kana PMOSFET.

Kushandisa bvunzo zvishandiso:Kuyera kupikiswa kwepini kweMOSFET kana mabatirwo ayo pamagetsi akasiyana kuburikidza nemidziyo yekuyedza senge mamultimeters inogona kubatsirawo pakuona mhando yayo.

Muchidimbu, kutonga kweNMOSFETs uye PMOSFETs kunogona kuitwa zvakanyanya kuburikidza neinoyerera mafambiro, parasitic diode direction, hukama pakati peiyo control electrode voltage uye conductivity, pamwe nekutarisa yekumaka mudziyo uye mashandisirwo ezviridzwa zvekuedza. Mukushandiswa kunoshanda, nzira yakakodzera yekutonga inogona kusarudzwa maererano nemamiriro chaiwo.
