Wazi kangakanani ngesimboli ye-MOSFET?

Iimpawu ze-MOSFET zihlala zisetyenziselwa ukubonisa ukudibanisa kwayo kunye neempawu ezisebenzayo kwisekethe.MOSFET, igama elipheleleyo le-Metal Oxide Semiconductor Field Effect Transistor (i-Metal Oxide Semiconductor Field Effect Transistor), luhlobo lwezixhobo ze-semiconductor ezilawulwa ngumbane, ezisetyenziswa ngokubanzi kwiisekethe zombane. .

Ii-MOSFET zahlulwe ikakhulu zibe ziindidi ezimbini: ii-N-channel MOSFETs (NMOS) kunye ne-P-channel MOSFETs (PMOS), nganye kuzo inophawu olwahlukileyo. Oku kulandelayo yinkcazo eneenkcukacha yezi ntlobo zimbini zeesimboli ze-MOSFET:

I-N-Channel MOSFET (NMOS)

Isimboli ye-NMOS idla ngokumelwa njengomfanekiso onezikhonkwane ezintathu, ezingamasango (G), idrain (D), kunye nomthombo (S). Kwisimboli, isango lihlala liphezulu, ngelixa i-drain kunye nomthombo iphantsi, kwaye i-drain idla ngokubhalwa njengepini kunye netolo ebonisa ukuba ulwalathiso oluphambili lokuhamba kwangoku luvela kumthombo ukuya kwi-drain. Nangona kunjalo, kubalulekile ukuqaphela ukuba kwimizobo yesekethe yokwenyani, isalathiso sotolo asinakuhlala sibhekisa kumbhobho, kuxhomekeke kwindlela isekethe idityaniswe ngayo.

IP-chaneli MOSFET (PMOS)

Iisimboli ze-PMOS ziyafana ne-NMOS kuba zikwanazo nemizobo enezikhonkwane ezintathu. Nangona kunjalo, kwi-PMOS, isalathiso sotolo kwisimboli sinokwahluka kuba uhlobo lomthwali luchasene ne-NMOS (imingxuma endaweni yee-electron), kodwa ayizizo zonke iisimboli ze-PMOS ezibhalwe ngokucacileyo ngendlela yotolo. Kwakhona, isango libekwe ngasentla kwaye i-drain kunye nomthombo uphantsi.

Iintlobo ngeentlobo zeeMpawu

Kubalulekile ukuqaphela ukuba iisimboli ze-MOSFET zinokuba nokwahluka okuthile kwisoftware okanye imigangatho yokudayagramu yesekethe. Umzekelo, ezinye iisimboli zinokushiya utolo ukwenza lula ukumelwa, okanye ukwahlula phakathi kweentlobo ezahlukeneyo zeMOSFET ngokusebenzisa izimbo zomgca ezahlukeneyo kunye nokuzalisa imibala.

Izilumkiso kwizicelo ezibonakalayo

Kwizicelo ezisebenzayo, ukongeza ekuqondeni iisimboli ze-MOSFETs, kukwayimfuneko ukunikela ingqalelo kwi-polarity yabo, inqanaba lombane, umthamo wangoku kunye nezinye iiparamitha zokuqinisekisa ukhetho oluchanekileyo kunye nokusetyenziswa. Ukongeza, ekubeni i-MOSFET sisixhobo esilawulwa ngamandla ombane, ingqwalasela eyodwa kufuneka ihlawulwe kulawulo lwamandla ombane wesango kunye namanyathelo okukhusela xa kuyilwa isekethe ukunqanda ukuqhekeka kwesango kunye nokunye ukusilela.

Isishwankathelo, isimboli ye-MOSFET kukumelwa kwayo okusisiseko kwisekethe, ngokuchongwa kweesimboli inokuqonda uhlobo lwe-MOSFET, uqhagamshelo lwephini kunye neempawu zokusebenza. Nangona kunjalo, kwizicelo ezibonakalayo, kukwayimfuneko ukudibanisa iimfuno ezithile zeesekethe kunye neeparamitha zesixhobo ukuze kuqwalaselwe ngokupheleleyo.
