Amateka y'iterambere ry'ikoranabuhanga ry'amajwi ashobora kugabanywamo ibice bine: umuyoboro, transistor, uruziga rwashyizwe hamwe na transistor y'ingaruka z'umurima.

Mu 1906, American de Forrest yavumbuye transistor ikoresha amashanyarazi, ari nayo yatangije ikoranabuhanga rya electro-acoustic ry’abantu. Bell Labs yavumbuwe mu 1927. Nyuma y’ikoranabuhanga rikoresha ibyuma bitanga amakuru mabi, iterambere ry’ikoranabuhanga ry’amajwi ryinjiye mu gihe gishya, nka Williamson amplifier yakoresheje neza ikoranabuhanga rikoresha ibyuma bitanga amakuru mabi kugira ngo bigabanye cyane uburyo amplifier yahindagurikaga kugeza mu myaka ya 1950, iterambere rya amplifier ya tube ryageze mu bihe bishimishije cyane, amplifier zitandukanye za tube zigaragara mu buryo budashira. Kubera ko ibara ry’amajwi rya amplifier ya tube ari ryiza kandi rizengurutse, iracyakundwa n’abayikunda.

Mu myaka ya 1960, kugaragara kwa transistors byatumye umubare munini w’abakunzi b’amajwi winjira mu isi yagutse y’amajwi. Amplifiers za transistors zifite imiterere yoroshye kandi igenda, kugorama guke, gusubiza inshuro nyinshi hamwe n’uburyo bwo guhindura imiterere y’amajwi.

Mu ntangiriro za 1960, Leta Zunze Ubumwe za Amerika zatangije bwa mbere imiyoboro ya "integrated circuits", ari nayo mishya mu ikoranabuhanga ry'amajwi. Mu ntangiriro za 1970, imiyoboro ya "integrated circuits" yagiye imenyekana buhoro buhoro n'inganda zikora amajwi kubera ubwiza bwayo bwo hejuru, igiciro cyayo kiri hasi, ingano nto, imikorere myinshi n'ibindi. Kugeza ubu, imiyoboro ya "integrated film audio" ikomeye hamwe n'imiyoboro ya "operational amplifier" byakoreshejwe cyane mu miyoboro ya "audio".

Hagati mu myaka ya 1970, Ubuyapani bwakoze umuyoboro wa mbere wo gusaba imikorere y’ingufu z ...
