Menene Integrated Circuit (IC)?
Kafin gano ICs, ainihin hanyar yin da'irori shine a zaɓi abubuwan da suka dace kamar diodes, transistor, resistors, inductor da capacitors da haɗa su ta hanyar kafada.Amma saboda girman da al'amurran da suka shafi amfani da wutar lantarki, ya zama dole don haɓaka ƙananan girman da'irar tare da ƙarancin amfani da wutar lantarki, aminci da abin tsoro.
Bayan ƙirƙirar semiconductor da transistor, abubuwa sun sauƙaƙa zuwa wani yanki na musamman, amma haɓakar haɗaɗɗun da'irori sun canza fuskar fasahar lantarki.Jack Kilby daga Texas Instruments da Bob Noyce daga Intel su ne mahaliccin haɗe-haɗen da'irori, kuma sun yi shi da kansu.
Haɗe-haɗen da'ira shine ainihin ra'ayi na kayan lantarki wanda ya ginu akan wasu mahimman abubuwan da aka tattauna a baya a cikin manhajar mu.Don haka, don yin la'akari da sauri, shiga cikin labaran da aka jera a ƙasa:
