Abstract
A fully integrated fundamental and push-push voltage controlled oscillators (VCOs) working in K-band with a large tuning range and a low phase noise fabricated in a 0.18 µm SiGe BiCMOS technology is presented. To achieve a wide tuning range while maintaining a low VCO tuning sensitivity (Kvco), the coupled LC tanks and digital tuning capacitors are used. The VCOs achieve a frequency tuning range (FTR) of 17% with a low phase noise consuming 7 mW from 1.8V voltage supply.
