Abstract :
This paper presents a novel approach to the implementation of voltage-controlled oscillators (VCOs) for quick turnaround time and reduced design costs while maintaining good phase noise performance. An LC tank oscillator topology is reported, manufactured in a SiGe 0.6 μm bipolar technology and implemented on a pre-defined component array. Two oscillators are targeted, one at 10 GHz and another at 7.6 GHz, both running from a 3.3 V power supply and drawing a current of 6 mA. The oscillators exhibit phase noise figures of -89 dBc/Hz and -93 dBc/Hz at 100 kHz offset respectively.
