Abstract
A low-phase-noise 0.35-mum CMOS push-push oscillator utilizing micromachined inductors is presented in this paper. With the micromachined high-Q inductors, the oscillator achieves an oscillating frequency of 30.9 GHz while exhibiting an output power of -4 dBm with a low phase noise of -102.3 dBc/Hz at 1-MHz offset and the figure of merit (FoM) of -171.4 dBc/Hz. The fundamental rejection is 30 dB. This oscillator achieves low phase noise, good FOM, high output power, and also demonstrates the highest operating frequency among previously published Si-based and GaAs-based VCOs using micromachined structures
