Imirongo ihuriweho 

Umuzunguruko uhuriweho (IC) ni chip ya semiconductor itwara ibice bito nka capacator, diode, transistors, na résistoriste.Ibi bice bito bikoreshwa mukubara no kubika amakuru hifashishijwe ikoranabuhanga cyangwa igereranya.Urashobora gutekereza kuri IC nka chip ntoya ishobora gukoreshwa nkumuzingi wuzuye, wizewe.Inzira ihuriweho ishobora kuba compteur, oscillator, amplifier, irembo ryumvikana, igihe, ububiko bwa mudasobwa, cyangwa na microprocessor.

IC ifatwa nkibyingenzi byubaka ibikoresho byose bya elegitoroniki.Izina ryayo ryerekana sisitemu yibice byinshi bihujwe byinjijwe mubintu bito, byakozwe na silicon yakozwe na semiconductor.

Amateka Yumuzunguruko

Ikoranabuhanga inyuma yumuzunguruko ryatangijwe bwa mbere mu 1950 na Robert Noyce na Jack Kilby muri Amerika.Ingabo zirwanira mu kirere z’Amerika nizo zabanje gukoresha iki gihangano gishya.Jack kandi Kilby yagiye gutsindira igihembo cyitiriwe Nobel muri fiziki mu 2000 kubera ko yahimbye IC nto.

Nyuma yimyaka 1.5 nyuma yo kumenyekanisha igishushanyo cya Kilby, Robert Noyce yerekanye verisiyo ye yumuzunguruko.Moderi ye yakemuye ibibazo byinshi bifatika mubikoresho bya Kilby.Noyce kandi yakoresheje silikoni kuri moderi ye, naho Jack Kilby yakoresheje germanium.

Robert Noyce na Jack Kilby bombi babonye patenti zamerika kubera uruhare rwabo mukuzunguruka.Barwanye nibibazo byamategeko imyaka myinshi.Hanyuma, ibigo byombi bya Noyce na Kilby byafashe icyemezo cyo kwambukiranya imipaka ibyo bahimbye no kubimenyekanisha ku isoko rinini ku isi.

Ubwoko bwumuzunguruko

Hariho ubwoko bubiri bwumuzunguruko.Aba ni:

1. Kugereranya IC

Analog ICs ihora isohora ibisohoka, bitewe nikimenyetso barimo.Mubyigisho, IC nkiyi irashobora kugera kuri leta zitagira imipaka.Muri ubu bwoko bwa IC, ibisohoka urwego rwimikorere ni umurongo wumurongo winjiza urwego rwibimenyetso.

Umurongo wa IC urashobora gukora nka radio-yumurongo (RF) hamwe na majwi-yumurongo (AF).Imikorere ya amplifier (op-amp) nigikoresho gisanzwe gikoreshwa hano.Mubyongeyeho, ubushyuhe bwubushyuhe nubundi buryo busanzwe bukoreshwa.Umurongo wa IC urashobora kuzimya ibikoresho bitandukanye no kuzimya iyo ikimenyetso kigeze ku gaciro runaka.Urashobora gusanga iri koranabuhanga mu ziko, ubushyuhe, hamwe nubushyuhe.

2. IC

Ibi bitandukanye na analogi IC.Ntabwo zikora kurwego ruhoraho rwibimenyetso.Ahubwo, bakora kurwego ruto rwashyizweho.Digital ICs ikora muburyo bwifashishije amarembo ya logique.Amarembo ya logique akoresha amakuru abiri.Ibimenyetso muri binary data bifite inzego ebyiri gusa zizwi nka hasi (logic 0) na high (logic 1).

Digital IC ikoreshwa muburyo butandukanye bwa porogaramu nka mudasobwa, modem, nibindi.

Ni ukubera iki Imirongo Yuzuzanya ikunzwe?

Nubwo yahimbwe hashize hafi imyaka 30, imiyoboro ihuriweho iracyakoreshwa mubikorwa byinshi.Reka tuganire kuri bimwe mubintu bishinzwe gukundwa kwabo:

1.Ubushobozi 

Mu myaka mike ishize, inganda za semiconductor zinjije zigera kuri miliyari 350 USD zidasanzwe.Intel niyo yatanze umusanzu munini hano.Hariho abandi bakinnyi nabo, kandi benshi muribo bari ab'isoko rya digitale.Iyo urebye imibare, uzabona ko 80 ku ijana byagurishijwe byakozwe ninganda ziciriritse zikomoka kuri iri soko.

Inzira zuzuye zagize uruhare runini muri iyi ntsinzi.Urabona, abashakashatsi binganda za semiconductor basesenguye umuzenguruko uhuriweho, imikoreshereze yawo, nibisobanuro byawo barawupima.
