Transistor-cirifoodka - unit aasaasiga ah ee jaha signallo koronto

In horumarka labadaba gudaha iyo kuwa caalamiga korontada iyo elektarooniga ciyaaray ah qalabka muhiimka ah doorka sida Semiconductor sida transistor-cirifoodka.

transistor-cirifoodka - qalab, isagoo in ay ka kooban laba Isgoyska pn xiran, wuxuu ku salaysan yahay qalabka Semiconductor. Noocan ah transistor waxay leedahay saddex boosteejada. Jaha sifooyinka, taas oo uu leeyahay transistor bipolar, sharaxay ku salaysan aqoonta ku hodanaynta iyo dhammaaday eedeeyay platelets Semiconductor (cirbad lagu qabtay iyo hababka fiirsato, siday u kala horreeyaan), iyo sidoo kale sharciyada electromagnetism.

Maanta waxaa jira laba nooc oo waaweyn oo transistors bipolar, kuwaas oo loo qoondeeyey si qaynuunka waafaqsan ayuu taas oo ay jirto iskhilaafka ah gobollada nooc oo kala duwan conductivity ee Semiconductor loo isticmaalo in saamiga: npn nooca iyo pnp. Faa'iidooyinka hal nooc ka badan kuwa kale oo aan la kala sooci karaa sababtoo ah farqiga u dhexeeya noocyada transistors waa kaliya waxa polarity ee isha dibadda xoog ku xiran mid ka mid ah ama qalab kale oo terminal.

Transistor - qalab bipolar ka kooban yahay saddex walxaad ugu muhiimsan: a ururiyaha, xataa salkeeda iyo emitter. Mid kasta oo ka cunsur ee ku xiran yahay, sida caadiga ah, mid ka mid ah terminal.

transistors-cirifoodka waxaa inta badan lagu tilmaamay inay by dhereg xoog, ka ururiyaha ka noqday. By dhimaya this qalab kala qaybsan yihiin transistors low-xoog (oo ku saabsan 0.3 W), dhexdhexaad ah (0.3 nus watt) iyo sare (1.5 watts). Mabda kale oo kala soocidda ee transistors - ee shaqada kala duwan oo soo noqnoqoshada. In qalabka sida mabda'a kala dhaadheer qalabka hooseeyo inta jeer (shan MHz), inta jeer dhexdhexaad ah (5 MHz 35 MHz), transistors HF (35 MHz si 350 MHz) iyo microwave (in ka badan 350MHz).

transistor kasta bipolar helo Calaamadayn waafaqsan heerarka qaranka ay khuseyso. Sida caadiga ah, magacaabista ah wuxuu ka kooban yahay lix ama toddoba characters (lambarada ama xarfaha). Sixitaanka waa tilmaamaya nooca wax, nooca qalab laftiisa, iyo sifooyinka noqnoqoshada qalab awood u ah. Sidoo kale, calaamadeynta go'aan ka gaari kara nooca iyo tirada serial horumarinta wax soo saarka ee. Sayidka, magacaabista ah ee transistor ah - baasaboor qalab, taas oo daaha ka dhan sifooyinka muhiimka ah ee qalabka.

Waxaa jira afar hababka aasaasiga ah ee hawlgalka transistor ku-cirifoodka:

• hab firfircoon oo marinka waa la furi waxayna xidhay at emitter in ay marinka ururinaysa;
• gooyaa-off, taas oo labada kala guurka (oo ah emitter iyo ururiyaha) way xiran yihiin iyo hadda aan la gudbay dhinaca hore,
• robab - xadka hab ka soo horjeeda ee ay u guurayso ururiyaha furan iyo emitter;
• inversion (mode rogay) - wajiga marka Isgoyska ururiyaha waa la furi waxayna emitter waxaa ku barakacay dhinaca ka soo horjeeda (ma gudbiya ah "toos ah" ee hadda).

Iyada oo ku xidhan ee electrodes ah (boosteejada) ee transistor uu noqonayo mid caadi ah in ay Cascades ah weyneeye iyo talooyin iyo wax soo saarka hadda, waxaa jira saddex nooc oo aasaasiga ah ee qalabka ka mid ah Bannaanka: transistor bipolar la emitter caadi ah, ururiyaha ama salka. Iyada oo ku xidhan nooca waxa of bedesheen qalabka loo isticmaalo in marxalad gaar ah, waxaad isticmaali kartaa faa'iidooyin kala duwan ee transistor ah.

Gebogebadii, waxaan la soco in maanta transistors bipolar hubkaas ayaa loo isticmaalaa in korontada iyo elektarooniga analog. Qalabka waxaa loo isticmaalaa noocyo kala duwan oo marxaladaha Faahfaahin iyaga oo aan u ma noqon doono suurto gal ah in la abuuro kordhiyo ah hawl - qalab in la oggol yahay si ay u abuuraan kala guurka ah ka analog in circuitry digital. Sidaa darteed, transistor ku bipolar la oran karo waa mid ka mid ah ugu aasaasiga ah ee qalabka Semiconductor, horumarinta aasaastay korantada oo casri ah.
