Abstract

Ovaj rad bavi se projektiranjem naponski upravljanog oscilatora i njegovom optimizacijom
s obzirom na potrošnju, raspon ugađanja i fazni šum. Oscilator je namijenjen za rad u
sintetizatoru frekvencije s dvostrukom petljom za ugađanje frekvencije temeljenog na
fazno zaključanoj petlji. Konstruiran je LC oscilator s parom unakrsno vezanih SiGe bipolarnih
tranzistora. Za kontinuirano ugađanje frekvencije koriste se MOS varaktori, a za diskretno
ugađanje binarni niz kapaciteta. Istražen je utjecaj zavojnice na fazni šum te je modelirana
zavojnica izrađena izvan čipa u tehnici sustava u pakiranju. Konstruiran je drugi oscilator s
modeliranom zavojnicom za usporedbu.

Abstract (english)

This thesis presents a voltage controlled oscillator that is optimized for use in dual-loop
frequency syntesizers based on phase locked-loop. Topology used is cross coupled SiGe bipolar LC oscillator with MOS varactors for continuous, and binary weighted capacitor array for
discrete frequency tuning. Oscillator is optimized based on tuning range and phase noise.
An off-chip inductor manufactured in innovative package technology is modeled. Its
impact on phase noise is demonstrated. Second oscillator is designed using modeled
inductor for comparison of phase noise.
