Uzifumanisa njani ii-nMOSFETs kunye nee-pMOSFETs

I. Ngokwesalathiso sokuhamba kwangoku

NI-MOSFET:Xa ngoku kuqukuqela ukusuka kumthombo (S) ukuya kumbhobho (D), i-MOSFET yi-NMOSFET Kwi-NMOSFET, umthombo kunye ne-drain zi-n-type semiconductors kwaye isango yi-p-type semiconductor. Xa i-voltage yesango ilungile ngokubhekiselele kumthombo, i-channel ye-n-type eqhubayo yenziwe phezu kwendawo ye-semiconductor, evumela ukuba ii-electron zihambe ukusuka kumthombo ukuya kwi-drain.

PI-MOSFET:I-MOSFET yi-PMOSFET xa umsinga wangoku uphuma kumbhobho (D) ukuya kumthombo (S) Kwi-PMOSFET, zombini umthombo kunye nedreyini zii-semiconductors zohlobo lwe-p kwaye isango yi-n-type semiconductor. Xa i-voltage yesango ingalunganga ngokubhekiselele kumthombo, i-p-type conducting channel yenziwa kumphezulu we-semiconductor, evumela imingxuma ukuba ihambe ukusuka kumthombo ukuya kwi-drain (qaphela ukuba kwinkcazo yesiqhelo sisatsho ukuba okwangoku isuka ku-D iye ku-S, kodwa eneneni isalathiso apho imingxunya ihamba).

II. Ngokutsho kwe-parasitic diode direction

NI-MOSFET:Xa i-parasitic diode yalatha kumthombo (S) ukuya kumanzi (D), yi-NMOSFET. I-parasitic diode sisakhiwo esingaphakathi kwi-MOSFET, kwaye isalathiso sayo sinokusinceda siqonde uhlobo lwe-MOSFET.

PI-MOSFET:I-parasitic diode yi-PMOSFET xa ikhomba ukusuka kwidrain (D) ukuya kwimvelaphi (S).

III. Ngokobudlelwane phakathi kolawulo lombane we-electrode kunye nokuhanjiswa kombane

NI-MOSFET:I-NMOSFET iqhuba xa amandla ombane esango elungile ngokubhekiselele kumbane womthombo. Oku kungenxa yokuba i-voltage yesango elungileyo idala i-n-type conducting channels kumphezulu we-semiconductor, evumela ukuba ii-electron zihambe.

PI-MOSFET:I-PMOSFET iqhuba xa amandla ombane esango alilunganga ngokumalunga nomthombo wombane. I-voltage yesango elibi lidala i-p-type conducting channel kwindawo ye-semiconductor, evumela imingxuma ukuba ihambe (okanye ikhoyo ngoku ukuba ihambe ukusuka ku-D ukuya ku-S).

IV. Ezinye iindlela ezincedisayo zokugweba

Jonga izixhobo zokuphawula:Kwezinye ii-MOSFETs, kusenokubakho inombolo yokumakisha okanye imodeli echaza uhlobo lwayo, kwaye ngokujongana nedatha yedatha efanelekileyo, unokuqinisekisa ukuba ngaba yi-NMOSFET okanye yi-PMOSFET.

Ukusetyenziswa kwezixhobo zovavanyo:Ukulinganisa ukuxhathisa kwephini ye-MOSFET okanye ukuqhutywa kwayo kwiivolthi ezahlukeneyo ngezixhobo zovavanyo ezifana nee-multimeters nako kunokunceda ekumiseleni uhlobo lwayo.

Isishwankathelo, ukugwetywa kwe-NMOSFETs kunye ne-PMOSFETs kunokuqhutywa ikakhulu ngesikhokelo sokuhamba kwangoku, i-parasitic diode direction, ubudlelwane phakathi kombane wolawulo lwe-electrode kunye ne-conductivity, kunye nokujonga ukumakishwa kwesixhobo kunye nokusetyenziswa kwezixhobo zovavanyo. Kwizicelo eziphathekayo, indlela yokugweba efanelekileyo inokukhethwa ngokwemeko ethile.
