MOSFET: kanthu ndi kuchuluka kwa mfundo ya

Kuphunzira katundu wa zinthu monga michenga yopangira zida zamagetsi ndi, analola kuti atulukira chosintha. Pa nthawi luso malonda kubala diodes, mos transistors, thyristors ndi zinthu zina. Iwo bwinobwino m'malo machubu zingalowe n'kulola kuzindikira maganizo kwambiri kufika. zigawo michenga yopangira zida zamagetsi ntchito muzochitika zones za moyo wathu. Imatithandiza pokonza ndalama yaikulu kwambiri mfundo pamaziko a makompyuta awo amapangidwa, matepi rekoda, ma TV, etc.

Popeza kuyambitsa wa transistor poyamba, ndipo iyo inali mu 1948 zapita nthawi yaitali. Panali Kusiyana kwa mchitidwe uwu: mfundo germanium, pakachitsulo, kunja zotsatira transistor kapena MOSFET. Onse a iwo ankagwiritsa ntchito zipangizo zamagetsi. Kuphunzira kwa katundu wa semiconductors sadzaleka nthawi yathu.

Maphunziro awa zinachititsa kuti zikamera wa totere chipangizo monga MOSFET. Mfundo ntchito zimachokera pa mfundo yakuti munda magetsi (choncho dzina lina - munda) zimasiyanasiyana pa madutsidwe wa padziko michenga yopangira zida zamagetsi wosanjikiza m'malire ndi dielectric lapansi. Mundawu ntchito mu madera a pakompyuta zolinga zosiyanasiyana. Mos transistor ali ndi kapangidwe amene amalola kuti kulimbikira pakati kuda ndi gwero kuchepetsa mchikakamizo cha ulamuliro chizindikiro zayamba kuti ziro.

katundu, ndi osiyana ndi ochititsa kuti "mpikisano". Ndi iwo amene yodziŵira tanthauzo lake.

• Mkulu ntchito zimatheka ndi miniaturizing pa galasi palokha ndipo katundu wake wapadera. Ichi ndi chifukwa mavuto mafakitale. Panopa, makhiristo amatuluka ndi 0,06 micron chipata.
• Kagulu kusintha capacitance chimathandiza zipangizozi ntchito mu madera mkulu pafupipafupi. Mwachitsanzo, LSI ndi ntchito zawo wakhala bwinobwino ntchito mu kuyankhulana yam'manja.
• Pafupifupi ziro kukana, amene ali MOSFET mu boma lotseguka, zikhoza kugwiritsidwa ntchito ngati makiyi amagetsi. Iwo akhoza ntchito mu madera kwa kupoletsa chizindikiro mkulu pafupipafupi kapena Kuthana zinthu monga amplifiers ntchito.
• zipangizo Wamphamvu wa mtundu uwu akhala bwino ntchito mu zigawo mphamvu ndipo akhoza m'gulu dera la kupatsidwa ulemu. Chitsanzo chabwino cha ntchito zawo, kungakhale ndi inverter.

Pamene angagwiritse ntchito ndi zinthu izi ndi zofunika kuganizira zina. MOSFETs amazindikira overvoltage ndi chigamulocho mosavuta ndithu. The inductance madera ambiri ntchito mkulu-liwiro Schottky diodes kwa kuwongola n'zosiyana voteji zimachitika, amene amapezeka pa kusintha.

Ziyembekezo ntchito zipangizozi lalikulu ndithu. Kuwonjezera luso kupanga awo ali pa njira kuchepetsa galasi (shutter makulitsidwe). Pang'onopang'ono akutulukira zipangizo kuti amatha kusamalira Motors wamphamvu kwambiri.
