Zithunzi za MOSFETsewera mbalimu kusintha maderandikuwongolera kuzungulira ndikuzimitsa ndikusintha kwazizindikiro.Zithunzi za MOSFET zitha kugawidwa mozama m'magulu awiri: N-channel ndi P-channel.
Mu njira ya NMOSFETdera, pini ya BEEP ndi yayikulu kuti ithandizire kuyankha kwa buzzer, komanso yotsika kuti muzimitse buzzer.P-channelMOSFETkuti muwongolere gawo lamagetsi la GPS ndikutsegula ndi kuzimitsa, pini ya GPS_PWR ndiyotsika ikayaka, gawo la GPS ndi yachibadwa magetsi, ndikukwera kuti gawo la GPS lizimitsidwa.
P-channelMOSFETmu gawo la N-mtundu wa silicon pagawo la P + lili ndi ziwiri: kukhetsa ndi gwero. Mizati iwiriyi siimayenderana wina ndi mzake, pamene pali magetsi okwanira omwe amawonjezedwa ku gwero pamene akhazikika, pamwamba pa N-mtundu wa silicon pansi pa chipata chidzatuluka ngati P-mtundu wosanjikiza, mu njira yolumikiza kukhetsa ndi gwero. . Kusintha voteji pachipata amasintha kachulukidwe mabowo mu njira, motero kusintha kukana njira. Izi zimatchedwa P-channel enhancement field effect transistor.
Makhalidwe a NMOS, ma Vgs bola ngati mtengo wake utakhala wokulirapo, womwe ungagwiritsidwe ntchito pagalimoto yotsika yotsika, malinga ngati magetsi a pachipata cha 4V kapena 10V pamzere.
Makhalidwe a PMOS, mosiyana ndi NMOS, adzayatsa malinga ngati Vgs ndi yocheperapo mtengo wake, ndipo ndiyoyenera kugwiritsidwa ntchito pamayendedwe apamwamba pomwe gwero likulumikizidwa ndi VCC. Komabe, chifukwa cha kuchuluka kwa mitundu yosinthira, kukana kwambiri komanso mtengo wokwera, ngakhale PMOS itha kugwiritsidwa ntchito mosavuta pagalimoto yokwera kwambiri, chifukwa chake pamagalimoto apamwamba, nthawi zambiri amagwiritsa ntchito NMOS.
Zonse,Zithunzi za MOSFETali ndi zopinga zambiri, amathandizira kulumikizana mwachindunji m'mabwalo, ndipo ndiosavuta kupanga mabwalo akulu ophatikizika.
