Maxay yihiin transistors Bannaanka

Tan iyo markii ay transistor-cirifoodka waa a classic seddex dhibcood, waxaa jira saddex siyaabood ee suurtagal ah ee waxa ay ka mid yihiin in circuit elektaroonik ah la tubada caadi ah iyo terminal outlet:

• saldhig caadiga ah (OB) - danab sare Wehliyaha gudbinta;
• a-emitter caadi ah (MA) - signal ah maqalka sida hadda iyo danab;
• caadi-ururiyaha (OC) - maqalka signal hadda.

In kasta oo ka mid ah saddex nooc oo wareeggeedii transistor bedesheen ah waxa ay jawaab kala duwan si ay signal la gelin, maxaa yeelay sifooyinka guurto ah ee xubno ay firfircoon ku xiran tahay xal gaar ah.

Scheme saldhig caadiga ah waa mid ka mid ah saddex febwari ee caadiga ah daraysa transistors-cirifoodka. Sida caadiga ah waxaa loo isticmaalaa sida kordhiyo kayd hadda ama danab. transistors noocan oo kale ah Bannaanka waxaa lagu gartaa in emitter halkan u dhaqmo sida circuit talooyin ah, signal saarka ah waxa laga soo qaatay ee ururiyaha oo salka "aasaas" in silig caadi ah. qaabeynta A la mid yihiin wareeggeedii Beddelashada FET in Sammeecado iridda caadi ah.

transistors Beddelashada Scheme ON guryaha heerkulka iyo inta jeer ee deggan kala duwan in ay bixiyaan tiirsanaanta yar oo xuduudaheedu ku (faa'iido danab, hadda, impedance aqbasho) by heerkulka oo ka mid ah xaaladaha deegaanka shaqada. khasaaraha ka mid ah circuit yar R _IN iyo maqnaanshaha cod hadda.

Scheme emitter caadi bixisaa faa'iidada aad u dheer oo soo saarta signal saarka rogay ah, kaas oo laga yaabaa in ay ku kala duwan caddaalad ah oo waaweyn. Wehliyaha gudbinta ee nidaamka this inta badan ku xiran tahay heerkulka hadda eexda ah, ku dheehan faa'iido dhabta ah waa xoogaa aan la saadaalin karin. transistors waxay bixiyaan circuit Beddelashada sare _BX R, Wehliyaha ee hadda iyo danab-weyneeye, lakala rogay signal la gelin, ka mid noqoshada sahlanaato. darrada waa dhibaatooyinka la xiriira sii kaxeeyo ah - suurtagalnimada of isxilqaamay ra'yi-celin wanaagsan dhalanrog dhacdaa for calaamadaha yar oo ay sabab u tahay talooyin ku yar kala duwan oo firfircoon.

Scheme ururiyaha caadi ah (sidoo kale loo yaqaan raacsane emitter ah ee korantada) waa mid ka mid ah saddex nooc oo transistors Bannaanka. Waa signal talooyin ku bixisey via silsilad salka, iyo wax soo saarka laga saaro resistor ku soo wareegi jiray emitter ah transistor ah. qaabeynta ah stage kordhiyo ee noocan oo kale ah waxaa badanaa loo isticmaalaa sida kayd danab a. Halkan salka transistor u adeegtaa sida circuit talooyin ah, kuwaas oo emitter waa wax soo saarka, iyo ururiyaha waa aasaas dhibic caadi ah, sidaa darteed nidaamka magaca. Analogs uma shaqayn karo sidii Beddelashada circuit FETs la outlet caadi ah. Faa'iidada ee habkan si caddaalad ah waa la gelin sare stage kordhiyo impedance iyo wax soo saarka ah hooseeya marka loo eego.

Dhammaan saddex transistors caadiga circuit bedesheen hubkaas ayaa loo isticmaalaa in circuitry ah, taas oo ku xidhan iyadaa ka mid ah qalabka elektarooniga ah iyo deegaan ee ay codsiga.
