Sammanfattning

A class-C CMOS harmonic VCO maximizes the oscillation amplitude by operating the active devices operating in class C, while the bias-current noise is naturally rejected by the topology. Drawing 1.4mA from a 1V supply, the 0.13µm CMOS prototype exhibits an average phase noise of -130dBc/Hz at 3MHz offset over the 4.90-to-5.65GHz tuning range, for an FoM of 194.5dBc/Hz.
