Voltage-controlled oscillator in the coil

In this paper we have examined the effect of devices inside an inductor through simulations and measurements. A voltage-controlled oscillator (VCO) was constructed inside an inductor using layout techniques that minimize eddy current loss and magnetic coupling. Measurement results show that this compact VCO has an equal performance in phase noise and output power as compared to a traditional VCO while reducing the area by about 50%.
