Ithiyori enxuseneyo yee-MOSFETs kunye neeTransistors

Malunga nethiyori esisiseko yee-transistors ezihambelanayo kunye ne-MOSFETs: Okokuqala, ii-transistors zinexabiso elibi lobushushu elichazayo, oko kukuthi, xa ubushushu be-transistor ngokwawo buphakama, ukuchasana kuya kuba kuncinci. Okwesibini, ii-MOSFET zinexabiso elincomekayo lobushushu elichasayo ngokungafaniyo neetransistors, okuthetha ukuba xa iqondo lobushushu linyuka, ukuxhathisa kuya kunyuka kancinci.

Xa kuthelekiswa neetransistors, ii-MOSFETs zifaneleke ngakumbi ukulinganisa okukhoyo kwiisekethe zamandla ezihambelanayo. Ke xa umsinga okhoyo kwisekethe yonikezelo lombane mkhulu, sicebisa ngokubanzi ukusetyenziswa kwee-MOSFETs ezinxuseneyo kwi-shunt. Xa sikhetha i-MOSFETs ukulinganisa okwangoku, kwaye kwenye yeendlela zangoku zidlula enye indlela ye-MOSFET yangoku, i-current ye-MOSFET ebangelwa ukushisa kwee-MOSFET ezinkulu, okuya kubangela ukuchasana kwe-on-off kuba kukhulu. , ukunciphisa ukuhla kwamandla akhoyo; I-MOSFETs esekwe kumahluko okwangoku ukulungelelanisa rhoqo, kwaye ekugqibeleni uqonde ibhalansi yangoku phakathi kwezi zimbiniIi-MOSFETs.

Enye yezinto ekufuneka siyiqaphele: iitransistors zinokudityaniswa ngokunxuseneyo ukugqiba ukuhamba kwempahla ephezulu yangoku, kodwa ke kufuneka kwakhona ukuba usekwe kwisiseko soluhlu lwe-resistor yokuqhuba ukujongana nebhalansi yangoku nganye. i-transistor ehambelanayo embindini wengxaki.

Iingxaki eziqhelekileyo zoqhagamshelo oluhambelanayo lwe-transistor:

(1), isango le-transistor nganye ayinakuqhagamshelwa ngokuthe ngqo kwi-resistor nganye ye-drive kuthotho ukuphumeza i-drive, ukwenzela ukuphepha ukujikeleza.

(2), ukwenza i-transistor nganye(MOSFET)ixesha elivulekileyo kunye nexesha lokuvala ukugcina ukuhambelana, kuba ukuba akuhambelani, eyokuqala ukuvula umbhobho okanye ukuvala umbhobho kuya kutshatyalaliswa ngenxa yokungena ngokugqithisileyo ngoku.

(3), yaye ekugqibeleni, singathanda ukuba nako kumthombo transistor nganye kuthotho kunye resistor elinganayo, Kakade ke, akuyomfuneko ukwenza, nje ukuba kunjalo.

U-Olueky uye waba yenye yezona arhente zikhula ngokukhawuleza kwaye zikhula ngokukhawuleza e-Asiya ngophuhliso lwentengiso olunobundlongondlongo kunye nokuhlanganiswa kwezixhobo ezifanelekileyo. Ukuba yeyona arhente ixabisekileyo ehlabathiniolukeyinjongo.
