摘要

switched coupled transmission line (SCTL) method with high Q and flexible structure is proposed for mm-wave VCO to improve tuning range ( TR ), meanwhile maintaining low phase noise, low power dissipation and zero additional area. This TR extension method is also proved effective in a switched coupled coplanar waveguide (SCCPW) VCO. Fabricated in 45 nm SOI CMOS, the SCTL-VCO achieves 38.74
