| 概要 | This paper proposes a pulse-tail-feedback technique for improving both 1/f2and 1/f3 noises. The proposed VCO has separated tail transistors driven by inverters with rail-to-rail voltage swing. The tail transistor has an impulse shaped current waveform to improve FoM, and the flicker noise up-conversion is reduced by the switching operation. A prototype of the proposed VCO is implemented in 180nm CMOS, and the VCO achieves an FoM of 195dBc/Hz from 10kHz-10MHz offset with a flicker noise corner of 700Hz at 4.55GHz oscillation.
