The proposed VCO presents an alternative approach to obtaining accurate quadrature phases by strategically modulating tail current sources while avoiding bimodal oscillations and noise due to coupling paths; the architecture is very compact, low power, robust and does not require tuning knobs. Demonstrated in a 40 nm CMOS process, the measured phase noise is -123.2 dBc/Hz at 1 MHz offset for an oscillation frequency of 4.9 GHz. The measured phase error at 4.9 GHz is 1.4°. A figure of merit (FoM) of 188.3 dBc/Hz was obtained while dissipating a power of 7.5 mW from a 1.1 V power supply. |
