A 1V 17GHz 5mW Quandrature CMOS VCO based on transformer coupling

A 1V 17GHz 5mW QVCO is designed using transformer coupling for high frequency, low voltage and low phase noise. Implemented in 0.18mum CMOS, the 0.37mm2 chip achieves a tuning range of 16.5% at 17GHz, a phase noise of -110dBc/Hz at 1MHz offset while using 5mA from a 1V supply, resulting in a FOM of 187.6dB
