MOSFET alamomin yawanci ana amfani da su don nuna haɗin kai da halayen aiki a cikin kewaye.MOSFET, cikakken suna Metal Oxide Semiconductor Field Effect Transistor (Metal Oxide Semiconductor Field Effect Transistor), nau'in na'urorin semiconductor ne mai sarrafa wutar lantarki, ana amfani dashi sosai a cikin da'irori na lantarki. .
MOSFETs an raba su zuwa rukuni biyu: MOSFETs N-channel (NMOS) da P-channel MOSFETs (PMOS), kowannensu yana da alama daban. Mai zuwa shine cikakken bayanin waɗannan nau'ikan alamomin MOSFET guda biyu:
N-Channel MOSFET (NMOS)
Alamar NMOS yawanci ana wakilta a matsayin adadi mai fil uku, waɗanda sune ƙofar (G), lambatu (D), da tushe (S). A cikin alamar, ƙofar yana yawanci a saman, yayin da magudanar ruwa da maɓuɓɓugar ruwa suke a ƙasa, kuma yawanci ana lakafta magudanar a matsayin fil tare da kibiya mai nuna cewa babban hanyar gudana a halin yanzu yana daga tushe zuwa magudanar. Duk da haka, yana da mahimmanci a lura cewa a ainihin zane-zane, alkiblar kibiya ba koyaushe tana nuni zuwa magudanar ruwa ba, ya danganta da yadda ake haɗa kewaye.
MOSFET P-tashar (PMOS)
Alamomin PMOS suna kama da NMOS a cikin cewa suna da hoto mai hoto tare da fil uku. Duk da haka, a cikin PMOS, jagorancin kibiya a cikin alamar zai iya bambanta saboda nau'in mai ɗauka shine akasin NMOS (ramuka maimakon electrons), amma ba duk alamun PMOS ba ne a fili aka lakafta tare da jagorancin kibiya. Bugu da ƙari, ƙofar yana sama kuma magudanar ruwa da tushen suna a ƙasa.
Bambance-bambancen Alamomi
Yana da mahimmanci a lura cewa alamun MOSFET na iya samun wasu bambance-bambance a cikin software na zane-zane daban-daban ko ma'auni. Misali, wasu alamomin na iya barin kibiyoyi don sauƙaƙa wakilci, ko bambanta tsakanin nau'ikan MOSFET daban-daban ta salon layi daban-daban da cika launuka.
Kariya a aikace aikace
A cikin aikace-aikacen aikace-aikacen, ban da sanin alamun MOSFETs, Hakanan wajibi ne a kula da polarity, matakin ƙarfin lantarki, ƙarfin halin yanzu da sauran sigogi don tabbatar da zaɓi da amfani daidai. Bugu da kari, tun da MOSFET na'ura ce mai sarrafa wutar lantarki, ana bukatar kulawa ta musamman ga sarrafa wutar lantarki da matakan kariya yayin zayyana da'ira don guje wa rushewar kofa da sauran gazawa.
A taƙaice, alamar MOSFET ita ce ainihin wakilcinta a cikin kewayawa, ta hanyar gano alamomin na iya fahimtar nau'in MOSFET, haɗin fil da halayen aiki. Koyaya, a aikace-aikace masu amfani, Hakanan ya zama dole a haɗa takamaiman buƙatun kewayawa da sigogin na'ura don cikakkiyar la'akari.
