Abstract

Suvremeni razvoj uporabe digitalnih ili potpuno digitalnih ciklusa s faznim podešavanjem (PLLs) u različitim uređajima za komunikaciju vodi ka primjeni digitalno kontroliranog oscilatora (DCO). U ovom se preglednom članku daje razvoj DCO-a u modernim elektroničkim uređajima kao i njihovo funkcioniranje u lokalnim oscilatorima. Iako se implementacija DCO preferira u odnosu na analogne, i dalje se radi na poboljšanjima u potrošnji energije, brzini, veličini čipa, raspona frekvencije, ulaznog napona, prenosivosti i rezolucije. U radu se uglavnom opisuje razvoj od oscilatora kontroliranih voltažom (voltage controlled oscillators- VCO) do digitalno kontroliranih oscilatora za "deep-submicrometer CMOS" postupak. Fokus je na analizi i praćenju unapređenja DCO-a na razini funkcionalnosti.
