A new enhanced swing class-D quadrature VCO which operates from a supply voltage as low as 350 mV is presented. The prototype 5 GHz VCO was fabricated in a 65 nm RF CMOS process. The measured phase noise performance is -137.1 dBc/Hz at 3 MHz offset with a power dissipation of 2.1 mW from a 0.35 V supply. The resulting figure-of-merit (FoM) is 198.3 dBc/Hz.(More)
A new enhanced swing class-D VCO which operates from a supply voltage as low as 300 mV is presented. The architectural advantages are described along with an analysis for the oscillation frequency. Prototype differential and quadrature variants of the proposed VCO have been implemented in a 65 nm RF CMOS process with a 5 GHz VCO oscillation frequency. At a(More)
