qalabka korontada shaqeeya si waafaqsan dabeecadihiisa u gaarka ah. iyaga oo isticmaalaya in design ah ee qalabka of kakanaanta kasta oo abuuri kara model xisaabeed qalab gaar ah. On mabda this abuuray barnaamijyada isticmaala Qaabaynta xisaabeed iyo noo oggolaan in ay arkaan shuqulka Bannaanka electronic shaashadda kormeeraha. Waxay si weyn u caawiyaan horumarinta qalabka. By xidhiidhinaya a ciidammadu dalwaddii kala duwan oscilloscopes, waxaa laga arki karaa waxqabadka waxyaabaha mustaqbalka iyo ka dhigi hagaajin haddii loo baahdo. Iyadoo ku saleysan, waa inaydaan baran karaa oo kaliya sida loo qorsheeyo qalabka elektarooniga ah, laakiin sidoo kale si ay u sahamiyaan qaar ka mid ah muuqaalada waxyaabaha, si qoto ay aqoon. Tusaale ahaan, mid ka mid ah waxyaabaha asaasiga ah ee korantada ku salaysan sifooyinka volt-ampere, diode oran VAC. qalabka way wanaagsan yihiin in ay jiraan dhawr cayn kasta oo iyaga ka mid. Dhamaan iyaga ka mid ah ayaa si guul leh loo isticmaalay wareeggeedii electronic. qalabka isu xaqiijiyay muddo sannado ah hawlgalka in qalabka ujeedooyin kala duwan.
The element ugu horeysay sida lagu soo shiriyey in a "tube vacuum" version oo muddo dheer laga adeegsado dhismaha nidaamyada kala duwan. aaladaha noocan oo kale ah waxaa loo isticmaalaa in Sammeecado tube, kuwaas oo weli ka soo saaray shirkadaha shakhsiga. diode CVC kiiskan waxa lagu tilmaamay by the-Langmuir Bogusławski. Sida laga soo xigtay formula this, hadda ka dhex maraya qalabka, danab si toos ah uu u dhigmaa awoodda saddex labaad by Wehliyaha waa tarmay. Sida aad arki karto, qaybta hore ee sifo diode leeyahay non-linearity. qalooca Tani waa "hagaajin" marka barta qalliinka ee ku soo koobin magacaaban ah.
Beegyada uu qalab Semiconductor u dhow yahay meel u dhow kaamil. Linearity ku xiran tahay qaybtii hore ee wax ka crystal la sameeyo. Sidoo kale muhiim ah waa xaddiga lacagta ee nijaasta ahaa, i.e. tayada alaabta ceeriin. CVC diode Semiconductor matali karaa sida qalooca ah in kala duwan qiyaastii aheyn oo uu leeyahay dhibic inflection ah ka hor inta ay ka baxayso si ay caan ku ah ka hawlgala. baarka The Silicon of dhibic qalliinka "jebiyo" heerka of 0.6-0.7 volts. Ugu dhow inay VAC qiimaha haboon ee diode Schottky ah, halkan dhibic baxo waxqabadka noqon doonaa ee gobolka of 0.2-0.4 volts. Laakiin maanka ku hayo in danab a of 50 volts, hantida this lumo.
The wax-u diode Zener leedahay qalooca ah, "reverse" element caadiga ah. Taasi waa, la sii kordhaya danab hadda ku ool ah ma u muuqdaan in ay gaaraan marinka gaar ah, ka dibna gebiyo korodho.
Soo-saarayaasha alaabta, kuwaas oo aan u muuqdaan in ay sheeg sifooyinka dhabta ah, sida ay kuwo ku kala duwan xitaa Dufcaddii isku mid yihiin. Intaa waxaa dheer, waxaad qaadan kartaa diode ah, kuwaas oo si sax ah CVC qiyaasay in shaybaarka iyo bedesho heerkulka hawlgalka ay. Iyo sifooyinka isbedelka. Caadi ahaan waxay muujinaysaa qaar ka mid ah ka baxsan howlgalka xasiloon element ka electronic, taas oo ku xidhan xaaladaha hawlgalka ay.
