Isingeniso
Ama-Transistors angamahhashi okusebenza kagesi wesimanje, akha amabhulokhi wokwakha wamadivayisi amaningi. Kodwa bewazi ukuthi ukuguqulwa okulula kungavula ukusebenza okusha kulezi zingxenye ezihlukahlukene? Faka i-transistor exhunywe nge-diode, indlela ehlakaniphile ekhulisa amandla e-basic transistor. Lokhu okuthunyelwe kwebhulogi kungena emhlabeni wama-transistors axhumeke kwi-diode, echaza umqondo wawo, umsebenzi wawo, nezinye izinhlelo zokusebenza ezimangalisayo kumasekhethi kagesi.
Ukuqonda i-Diode-Connected Transistor
Cabanga nge-bipolar junction transistor (BJT) evamile. Inamatheminali amathathu: isisekelo, umqoqi, kanye ne-emitter. Ekucushweni okujwayelekile, ukusebenzisa i-voltage kusisekelo kulawula ukugeleza kwamanje phakathi komqoqi kanye ne-emitter. Kodwa-ke, ku-transistor exhunywe nge-diode, isisekelo kanye nomqoqi zixhunywe ngaphakathi noma ngaphandle, ngokuyisisekelo kudala i-terminal eyodwa. Lokhu kuguqulwa okulula kuguqula i-transistor ibe yi-resistor elawulwa yi-voltage, lapho i-voltage esetshenzisiwe ku-terminal emitter esele inquma ukumelana.
Isebenza Kanjani?
Uma kujoyiniwe isisekelo nomqoqi, i-transistor isebenza kulokho okubizwa ngokuthi isifunda sokubheka phambili. Lapho i-voltage isetshenziswa ku-emitter, i-current iqala ukugeleza. Nokho, ngokungafani ne-transistor evamile, i-current ayikhuliswanga. Esikhundleni salokho, ukumelana phakathi kwe-emitter kanye netheminali ye-base-collector ehlanganisiwe kuyashintsha ngokusekelwe ku-voltage esetshenzisiwe. Lokhu kumelana okuguquguqukayo kuvumela izinhlelo zokusebenza ezithokozisayo kumasekethe kagesi.
Ukukhulula Amandla: Izinhlelo zokusebenza ze-Diode-Connected Transistors
Ikhono lokulawula ukumelana ne-voltage livula iminyango yemisebenzi ehlukahlukene:
Izibuko Zamanje: Lawa masekethi ahlakaniphile asebenzisa ama-transistors axhunywe nge-diode ukuze enze umfanekiso onembile wokufakwayo kwamanje. Lokhu kubalulekile ezinhlelweni ezinjengokucubungula isignali ye-analog kanye nokwakhiwa kwesekethe edidiyelwe.
Ama-Level Shifters: Kwesinye isikhathi, amasekhethi e-elekthronikhi asebenza emazingeni ahlukene kagesi. Ama-transistors axhumeke kwi-diode angasetshenziswa ukushintsha isignali kagesi ezingeni elihlukile, ukuqinisekisa ukuhambisana phakathi kwezingxenye.
Isinxephezelo Sezinga Lokushisa: Ezinye izingxenye ze-elekthronikhi zingazwela ekushintshashintsheni kwezinga lokushisa. Ama-transistors axhumeke nge-diode angasetshenziswa ukunxephezela lezi zinguquko ngokulungisa ukumelana ngokuzenzakalela.
Isiphetho
I-transistor exhunywe nge-diode ingase ibonakale njengokuguqulwa okulula, kodwa ivula umhlaba wamathuba emklamo wesifunda se-elekthronikhi. Ngokuqonda ukuthi isebenza kanjani kanye nezinhlelo zokusebenza ezihlukene, uthola ukwazisa okujulile kokuguquguquka kwama-transistors kanye nendima yawo ekubumbeni ubuchwepheshe besimanje. Ufuna ukwandisa ulwazi lwakho lwezingxenye ze-elekthronikhi nomklamo wesifunda? Hlola izinsiza zethu ezibanzi kanye nezifundo!
