| Abstract: | A novel idea for the improvement of phase noise in differential LC-VCOs with no degradation of power consumption is proposed. Being based on purification of inductors to enhance the quality factor (Q), the application of the idea in design of CMOS based Giga Hertz (GHz) range low power and low phase noise monolithic differential LC-VCOs is illustrated and analyzed. Post-layout simulations using CMOS 0.18 μm TSMC RF design kit are used for evaluation. |
