Kev sib txuas ntawm MOSFETs thiab Field Effect Transistors

Kev lag luam khoom siv hluav taws xob tau txais mus rau qhov chaw tam sim no yam tsis muaj kev pabMOSFETsthiab Field Effect Transistors. Txawm li cas los xij, rau qee tus neeg tshiab rau kev lag luam hluav taws xob, nws feem ntau yooj yim kom tsis meej pem MOSFETs thiab teb cov nyhuv transistors.Dab tsi yog qhov kev sib txuas tom qab MOSFETs thiab teb cov nyhuv transistors?Puas yog MOSFET lub teb cuam tshuam los yog tsis?

Qhov tseeb, raws li kev suav nrog cov khoom siv hluav taws xob no, hais tias MOSFET yog qhov cuam tshuam ntawm transistor tsis muaj teeb meem, tab sis lwm txoj hauv kev tsis raug, uas yog hais tias, thaj chaw cuam tshuam transistor tsis tsuas yog suav nrog MOSFET, tab sis kuj suav nrog. lwm yam khoom siv hluav taws xob.

Field effect transistors tuaj yeem muab faib ua cov raj sib txuas thiab MOSFETs. Piv nrog rau MOSFETs, junction tubes siv tsawg zaus, yog li qhov zaus ntawm kev hais txog cov raj sib txuas kuj tseem tsawg, thiab MOSFETs thiab cov nyhuv cuam tshuam feem ntau tau hais, yog li nws yooj yim rau kev nkag siab yuam kev tias lawv yog tib yam ntawm cov khoom.

MOSFETtuaj yeem muab faib ua hom kev txhim kho thiab hom depletion, txoj hauv kev ua haujlwm ntawm ob lub tshuab hluav taws xob no sib txawv me ntsis, txhim kho hom raj hauv lub rooj vag (G) ntxiv rau qhov zoo voltage, ntws (D) thiab qhov chaw (S) kom coj, thaum lub depletion hom txawm tias lub rooj vag (G) tsis ntxiv rau qhov zoo voltage, qhov ntws (D) thiab qhov (S) kuj yog conductive.

Ntawm no qhov kev faib tawm ntawm thaj chaw cuam tshuam transistor tsis dhau, txhua hom raj tuaj yeem muab faib ua N-hom raj thiab P-hom raj, yog li lub teb cov nyhuv transistor tuaj yeem muab faib ua rau rau hom kav dej hauv qab no, raws li, N-channel. P-channel junction field effect transistors, N-channel txhim kho cov nyhuv transistors, P-channel txhim kho cov nyhuv transistors, N-channel depletion field effect transistors, thiab P-channel depletion hom Field Effect Transistors.

Txhua yam khoom nyob rau hauv daim duab kos duab ntawm cov cim Circuit Court yog txawv, piv txwv li, daim duab hauv qab no teev cov cim hauv Circuit Court ntawm ob hom kev sib tshuam, tus lej 2 tus pin xub taw qhia rau lub raj rau N-channel junction field effect transistor. , taw qhia sab nraud yog P-channel junction teb cov nyhuv transistor.

MOSFETthiab junction tube Circuit Court sib txawv yog tseem loj, N-channel depletion hom teb cov nyhuv transistor thiab P-channel depletion hom teb nyhuv transistor, tib xub taw tes rau cov yeeb nkab rau N-hom, taw tawm sab nraud yog P-hom raj. . Ib yam li ntawd, qhov sib txawv ntawm N-channel kev txhim kho hom teb cov nyhuv transistors thiab P-channel txhim kho hom teb cov nyhuv transistors kuj yog raws li qhov taw qhia ntawm xub, taw rau cov yeeb nkab yog N-hom, thiab taw qhia sab nraud yog P-hom.

Txhim kho qhov cuam tshuam cov nyhuv transistors (xws li N-hom raj thiab P-hom raj) thiab depletion field effect transistors (xws li N-hom raj thiab P-hom raj) cov cim Circuit Court yog ze heev. Qhov sib txawv ntawm ob yog tias ib qho ntawm cov cim yog sawv cev los ntawm ib txoj kab dashed thiab lwm yam los ntawm cov kab khoom. Cov kab dotted qhia txog kev txhim kho thaj tsam cuam tshuam transistor thiab cov kab khoom qhia tau hais tias muaj kev cuam tshuam cov nyhuv transistor.
