摘要：

A fully integrated push- push voltage controlled oscillator (VCO) working in K- band with a large tuning range and a low phase noise fabricated in a 0.18 mu m SiGe BiCMOS technology is presented. Multi- coupled LC tanks are used to improve the tuning range, power consumption and phase noise. Digital tuning varactors are used to maintain a low VCO tuning sensitivity (K-VCO) and maximum frequency overlap. The VCO achieves a frequency tuning range (FTR) of 17% at 12 GHz, a phase noise of -106.62 dBc/Hz at 1MHz o r set and consumes 7mW from 1.8V supply.
