Abstract
This work presents a 60 GHz octa-core push-push VCO in a 45 nm partially depleted (PD) Silicon-on-Insulator (SOI) CMOS technology. We investigate the feasibility of coupling eight VCO cores via resonant-tank transformers and discuss circuit topology considerations. The measured phase noise at 63.4 GHz is -95.3dB/Hz at 1 MHz offset from carrier. The continuous frequency-tuning range is 19 %. The eight VCO cores consume in total 80 mW DC power. The complete circuit, including buffers at the fundamental and second harmonic outputs, draws 158 mA from a single 1 V supply. The total area of the octa-core VCO excluding pads is 0.18 mm 2 .
