Abstract :
A voltage controlled oscillator (VCO) based on the rotary traveling wave principle is presented. Its advantages are easy and accurate high frequency quadrature signal generation, adiabatic operation, and good phase noise properties. The VCO is realized with the commercially available TSMC 0.13/spl mu/m CMOS process. The 18-GHz VCO has a tuning range of 1GHz. The phase noise power spectral density observed is-117 dBc/Hz at a 1-MHz offset from the carrier. The complete circuit including buffers consumes 24nW from a 1.2V power supply. The die without pads occupies 0.12/spl mu/m/sup 2/.
