Indlela yokunquma i-MOSFET enamandla amakhulu ishiswa ngokutubeka

(1) I-MOSFET iyinto elawula amandla kagesi, kuyilapho i-transistor iyisici esilawulayo samanje. Ekhonweni lokushayela alitholakali, idrayivu yamanje incane kakhulu, kufanele ikhethweI-MOSFET; futhi ku-voltage yesignali iphansi, futhi ithembise ukuthatha amandla amaningi kusukela ezimeni zokushayela umshini wokudoba kagesi, kufanele kukhethwe i-transistor.

(2) I-MOSFET ukusetshenziswa kwezinkampani eziningi ezithwalayo, ezibizwa ngokuthi i-unipolar device, kuyilapho i-transistor iwukuthi kuneningi labathwali, kodwa futhi nokusetshenziswa kwenani elincane labathwali be-conductive. Ibizwa nge-bipolar device.

(3) AbanyeI-MOSFET umthombo kanye ne-drain ingashintshwa ukuze kusetshenziswe i-voltage yesango ingaba yinhle noma ibe yimbi, ukuguquguquka kwe-transistor kuhle.

(4) I-MOSFET ingasebenza ngaphansi kwezimo zamanje ezincane kakhulu neziphansi kakhulu, futhi inqubo yayo yokukhiqiza ingaba lula kakhulu ukuhlanganisa ama-MOSFET amaningi ku-silicon chip, ngakho-ke ama-MOSFET kumasekethe amakhulu ahlanganisiwe asetshenziswe kabanzi.

(5) I-MOSFET inezinzuzo zokuthikamezeka kokufaka okuphezulu nomsindo ophansi, ngakho-ke isetshenziswa kabanzi ezinhlobonhlobo zemishini yokucupha kagesi. Ikakhulukazi ne-field effect tube ukwenza yonke imishini kagesi okokufaka, okukhipha isigaba, angathola transistor jikelele kunzima ukufinyelela umsebenzi.

(6)Ama-MOSFET ahlukaniswe abe izigaba ezimbili: uhlobo lwe-junction ebomvu kanye nohlobo lwesango elihlanganisiwe, futhi izimiso zabo zokukhohlisa ziyefana.

Eqinisweni, i-triode ishibhile futhi isebenziseka kalula, evame ukusetshenziswa kubadobi bakudala be-low-frequency, i-MOSFET kumasekhethi anesivinini esiphezulu, izikhathi zamanje, ngakho uhlobo olusha lwabadobi be-high-frequency ultrasonic, lubalulekile. yiMOS omkhulu. ngokuvamile, izikhathi ezingabizi kakhulu, ukusetshenziswa okujwayelekile kokuqala ukucabangela ukusetshenziswa kwama-transistors, hhayi uma ufuna ukucabangela i-MOS.

I-MOSFET yizizathu zokuhlukaniswa futhi izixazululo zimi kanje

Okokuqala, ukumelana okokufaka kwe-MOSFET ngokwayo kuphezulu kakhulu, futhi isango - umthombo we-inter-electrode capacitance lincane kakhulu, ngakho-ke lingenwa kalula izinkambu zangaphandle ze-electromagnetic noma i-electrostatic inductance kanye nokushajwa, futhi inani elincane lenkokhelo lingakhiwa. ku-inter-electrode capacitance ye-voltage ephezulu ngokufanele (U = Q / C), izolimala ishubhu. Nakuba okokufaka kwe-MOS komshini wokudoba kagesi kunezinyathelo zokulungisa i-anti-static, kodwa kusadingeka ukuphathwa ngokucophelela, ekugcinweni nasekulethweni kweziqukathi zensimbi ezingcono kakhulu noma ukupakishwa kwezinto eziqhutshwayo, ungafaki kalula ukuhlasela i-static high voltage. izinto zamakhemikhali noma izindwangu ze-fiber zamakhemikhali. Ukuhlanganisa, ukugunyazwa, izinto, ukubukeka, indawo yokusebenza, njll. kufanele kube isisekelo esivelele. Ukuze ugweme ukulimala kokuphazamiseka komshini kagesi, okufana nokungafanele ukugqoka inayiloni, izingubo zefiber yekhemikhali, isandla noma okuthile ngaphambi kokuthinta ibhulokhi ehlanganisiwe kungcono ukuxhuma phansi. Emishinini ehola ukuqondisa nokugoba noma i-welding manual, ukusetshenziswa kwemishini kuyadingeka ukuze kubekwe phansi okuvelele.
