Umahluko phakathi kweDiode yoMzimba kunye neMOSFET-Olukey

I-diode yomzimba (edla ngokubizwa ngokuba yi-diode eqhelekileyo, njengegama“idiode yomzimba”ayisetyenziswa ngokuqhelekileyo kwiimeko eziqhelekileyo kwaye ingabhekisa kuphawu okanye kwisakhiwo sediode ngokwayo; nangona kunjalo, ngenxa yale njongo, sicinga ukuba ibhekisela kwi-diode eqhelekileyo) kunye ne-MOSFET (i-Metal Oxide Semiconductor Field Effect Transistor) yahluke kakhulu kwiinkalo ezininzi. Ngezantsi lucazululo oluneenkcukacha lweeyantlukwano zabo:

1. IiNkcazo eziSisiseko kunye neZakhiwo

- I-Diode: I-diode yisixhobo se-semiconductor esine-electrode ezimbini, ezenziwe nge-P-type kunye ne-N-type semiconductors, eyenza i-PN junction. Ivumela kuphela ukuba ikhoyo ihambe ukusuka kwicala elilungileyo ukuya kwicala elingalunganga (i-bias phambili) ngelixa ivimba ukujikeleza umva (i-bias eguqukayo).

- I-MOSFET: I-MOSFET sisixhobo semiconductor ye-threminal esisebenzisa umphumo wombane wokulawula umbane. Iquka isango (G), umthombo (S), kunye nomsele (D). Okwangoku phakathi komthombo kunye ne-drain ilawulwa ngumbane wesango.

2. UmGaqo wokuSebenza

- I-Diode: Umgaqo-siseko wokusebenza we-diode usekelwe kwi-conductivity unidirectional ye-PN junction. Ngaphantsi kwe-bias yangaphambili, abathwali (imingxuma kunye nee-electron) basasazeka kwi-PN junction ukuze benze umsinga; phantsi kwe-bias reverse, umqobo onokuthi udalwe, ukuthintela ukuhamba kwangoku.

- I-MOSFET: Umgaqo wokusebenza we-MOSFET usekwe kwisiphumo sommandla wombane. Xa i-voltage yesango ishintsha, yenza i-channel conductive (i-N-channel okanye i-P-channel) ebusweni be-semiconductor phantsi kwesango, ilawula umbane phakathi komthombo kunye ne-drain. Ii-MOSFET zizixhobo ezilawulwa ngamandla ombane, kunye nemveliso yangoku ngokuxhomekeke kumbane wegalelo.

3. Iimpawu zoMsebenzi

-Diode:

-Ifanelekile kwi-high-frequency kunye nezicelo zamandla aphantsi.

-Une-conductivity ye-unidirectional, eyenza ibe yinto ephambili ekulungiseni, ekubhaqweni, kunye neesekethe zokulawula umbane.

-I-voltage yokubuya umva yiparamitha ebalulekileyo kwaye kufuneka ithathelwe ingqalelo kuyilo ukunqanda imiba ebuya umva yokuqhekeka.

-MOSFET:

-Ine-impedance ephezulu, ingxolo ephantsi, ukusetyenziswa kwamandla aphantsi, kunye nokuzinza okuhle kwe-thermal.

-Ifanelekile kwiisekethe ezinkulu ezidibeneyo kunye nombane wombane.

- Ii-MOSFET zahlulwe zaba ziindidi ze-N-channel kunye ne-P-channel, nganye kuzo iza ngeendlela zokuphucula kunye ne-depletion-mode.

- Ibonisa iimpawu ezintle zangoku eziqhubekayo, kunye neendawo ezihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala khona.

4. Iinkalo zeSicelo

-I-Diode: Isetyenziswa kakhulu kwi-electronics, unxibelelwano, kunye neendawo zobonelelo lwamandla, njengakwiisekethe zokulungisa, iisekethe zolawulo lombane, kunye neesekethe zokubona.

I-MOSFET: Idlala indima ebalulekileyo kwiisekethe ezidibeneyo, i-elektroniki yamandla, iikhomputha, kunye nonxibelelwano, olusetyenziswa njengezinto zokutshintsha, izinto zokukhulisa, kunye nezinto zokuqhuba.

5. Isiphelo

IiDiodes kunye ne-MOSFETs ziyahluka kwiinkcazo zazo ezisisiseko, izakhiwo, imigaqo yokusebenza, iimpawu zokusebenza, kunye nemimandla yesicelo. Ii-Diodes zidlala indima ephambili ekulungiseni nasekulawuleni i-voltage ngenxa ye-unidirectional conductivity, ngelixa ii-MOSFET zisetyenziswa ngokubanzi kwiisekethe ezidibeneyo kunye nombane wamandla ngenxa ye-impedance yabo ephezulu, ingxolo ephantsi, kunye nokusetyenziswa kwamandla aphantsi. Omabini la macandelo abalulekile kubuchwephesha banamhlanje, ngalinye lineengenelo zalo.
