An eight-phase in-phase injection-coupled voltage-controlled oscillator (VCO) is presented in this letter. In the proposed VCO, in-phase coupling is realized through a symmetrical coupling network to obtain low phase noise and wide tuning range simultaneously. Implemented in 65-nm CMOS technology, the proposed VCO achieves tuning range of 73.5-81.4 GHz, phase noise of -100 dBc/Hz, and figure-of-merit value of -179.7 dBc/Hz both at 1-MHz offset frequency. Occupying about 0.1 mm(2) area, the power consumption of the proposed VCO is 61.5 mW including output buffers.
