Sidee loo doortaa wareegga darawalka ugu habboon MOSFET?

Dareemada korantada iyo barnaamijka naqshadaynta nidaamka sahayda korontada ee kale, naqshadeeyayaasha barnaamijku waxay fiiro gaar ah u yeelan doonaan tiro ka mid ah xuduudaha waaweyn eeMOSFET, sida resistor-ka-off, danab shaqaynaya oo weyn, socodka korantada oo weyn. Inkastoo element this waadhaliil, iyada oo la tixgelinayo meesha aan habboonayn waxay ka dhigi doontaa wareegga korantada ee aan si fiican u shaqeyn karin, laakiin dhab ahaantii, tani waa la dhammeeyaa oo kaliya tallaabada ugu horreysa,MOSFET Halbeegyada dulinnada ayaa loo arkaa inay yihiin waxa muhiimka ah ee khatar gelinaya wareegga sahayda korontada.

Sida loo doorto wareegga darawalka ugu habboon MOSFET

Wadista MOSFET-yada degdega ah ee leh korontadu ICs

 

Wareegga darawalka MOSFET ee wanaagsan wuxuu leeyahay qodobada soo socda:

(1) Isla marka uu daaran yahay dareewalka, wareegga darawalku waa inuu awood u yeeshaa inuu soo saaro koronto aad u weyn, si ay MOSFET-source-source inter-pole danabku si degdeg ah ugu kaco qiimaha loo baahan yahay, si loo hubiyo in furaha la rogi karo. si degdeg ah oo ma jiri doonaan gariirada soo noqnoqda sare ee cidhifka sare u kaca.

(2) wakhtiga daminta iyo daminta korantada, wareegtada wadista waxay xaqiijin kartaa in Ilaha MOSFET danab ka dhexeeya tiirarka ka shaqeeya la hayo muddo dheer, iyo habayn waxtar leh.

(3) Xir daqiiqad ka mid ah wareegga wadista, waxay siin kartaa kanaalka impedance hooseeya ee awoodda ilaha albaabka MOSFET ee u dhexeeya qulqulka degdegga ah, si loo hubiyo in daaranku si dhakhso ah loo dami karo.

Sida loo doorto wareegga darawalka ugu habboon MOSFET(1)

(4) Dhismo fudud oo la isku hallayn karo oo ah wareegyada wadista oo leh daal iyo dillaac hooseeya.

(5) Marka loo eego xaaladda gaarka ah si loo fuliyo ilaalinta.

Qalabka korantada ee moduleka kantaroolka, kan ugu caansan waa sahayda korantada ee IC si toos ah MOSFET. Codsiga, waa in fiiro gaar ah u leh waditaanka weyn ee qiimaha ugu sarreeya ee socodka korantada, awoodda qaybinta MOSFET 2 cabbirada waaweyn. Awoodda wadista awoodda IC, cabbirka awoodda qaybinta MOS, qiimaha iska caabbinta waduhu waxay khatar gelinaysaa heerka beddelka awoodda MOSFET. Haddii xulashada awoodda qaybinta MOSFET ay tahay mid aad u weyn, awoodda sahayda korantada ee IC awoodda wadista gudaha kuma filna, waa inay ku jirtaa wareegga wadista si loo hagaajiyo awoodda wadista, badiyaa codso wareegga sahayda koronto ee totem-ka si kor loogu qaado awoodda awoodda darawalnimada IC .
