Zizindikiro za MOSFET nthawi zambiri zimagwiritsidwa ntchito kusonyeza kugwirizana kwake ndi makhalidwe ake ogwira ntchito mu circuit.MOSFET, dzina lonse la Metal Oxide Semiconductor Field Effect Transistor (Metal Oxide Semiconductor Field Effect Transistor), ndi mtundu wa zipangizo zoyendetsedwa ndi magetsi zoyendetsedwa ndi magetsi, zomwe zimagwiritsidwa ntchito kwambiri pamagetsi amagetsi. .
Ma MOSFET amagawidwa makamaka m'magulu awiri: N-channel MOSFETs (NMOS) ndi P-channel MOSFETs (PMOS), iliyonse ili ndi chizindikiro chosiyana. Zotsatirazi ndikulongosola mwatsatanetsatane mitundu iwiri ya zizindikiro za MOSFET:
N-Channel MOSFET (NMOS)
Chizindikiro cha NMOS nthawi zambiri chimaimiridwa ngati chithunzi chokhala ndi zikhomo zitatu, zomwe ndi chipata (G), kukhetsa (D), ndi gwero (S). Pachizindikirocho, chipata chimakhala pamwamba, pamene kukhetsa ndi gwero kumakhala pansi, ndipo kukhetsa nthawi zambiri kumalembedwa ngati pini yokhala ndi muvi wosonyeza kuti njira yaikulu yomwe ikuyenda panopa imachokera ku gwero mpaka kukhetsa. Komabe, ndikofunika kuzindikira kuti muzithunzi zenizeni za dera, njira ya muviyo sikungakhale ikuloza kukhetsa, malingana ndi momwe dera likugwirizanirana.
P-channel MOSFET (PMOS)
Zizindikiro za PMOS ndizofanana ndi NMOS chifukwa zilinso ndi chithunzi chokhala ndi mapini atatu. Komabe, mu PMOS, mayendedwe a muvi pachizindikirocho akhoza kukhala osiyana chifukwa mtundu wonyamulira ndi wosiyana ndi NMOS (mabowo m'malo mwa ma electron), koma si zizindikiro zonse za PMOS zomwe zimalembedwa momveka bwino ndi njira ya muvi. Apanso, chipata chili pamwamba ndipo kukhetsa ndi gwero zili pansipa.
Zosiyanasiyana za Zizindikiro
Ndikofunikira kudziwa kuti zizindikilo za MOSFET zitha kukhala ndi zosintha zina pamapulogalamu osiyanasiyana ojambulira madera kapena miyezo. Mwachitsanzo, zizindikiro zina zimatha kusiya mivi kuti ziwonetsedwe mosavuta, kapena kusiyanitsa mitundu yosiyanasiyana ya ma MOSFET kudzera mumizere yosiyana ndi mitundu yodzaza.
Njira zodzitetezera pakugwiritsa ntchito
Muzogwiritsira ntchito, kuwonjezera pa kuzindikira zizindikiro za MOSFETs, m'pofunikanso kumvetsera polarity yawo, mlingo wamagetsi, mphamvu zamakono ndi zina kuti zitsimikizire kusankhidwa kolondola ndi ntchito. Kuphatikiza apo, popeza MOSFET ndi chipangizo choyendetsedwa ndi ma voltage, chidwi chapadera chiyenera kuperekedwa pakuwongolera magetsi pachipata ndi njira zodzitetezera popanga dera kuti zisawonongeke zipata ndi zolephera zina.
Mwachidule, chizindikiro cha MOSFET ndiye choyimira chake choyambira kuzungulira, kudzera pakuzindikiritsa zizindikiro zimatha kumvetsetsa mtundu wa MOSFET, kulumikizana kwa pini ndi mawonekedwe ogwirira ntchito. Komabe, pamagwiritsidwe ntchito, ndikofunikiranso kuphatikiza zofunikira zadera ndi magawo a chipangizo kuti muganizire mozama.
