A wide-tuning range voltage-controlled oscillator (VCO) with adjustable ground-plate inductor for ultra-wide band (UWB) application is presented in this paper. The VCO was implemented by standard 90nm CMOS process at 1.2V supply voltage and power consumption of 6mW. The tuning range from 13.3 GHz to 15.6 GHz with phase noise between -99.98 and -115dBc/Hz@1MHz is obtained. The output power is around -8.7 to -9.6dBm and chip area of 0.77x0.62mm2.

Class C

In this paper, a new class-C voltage-controlled oscillator (VCO) is presented. In the proposed VCO, the tail capacitor of the conventional class-C oscillator is dislocated from the source of the cross-coupled transistors to their gate to achieve a rail-to-rail output swing. This improves the phase noise by 2.9 dB compared to the conventional class-C one. Besides, a new switching scheme is presented in the switched capacitor bank used for coarse tuning of the proposed VCO to lower the on resistance of the switches as well as to reduce the parasitic capacitors. This wide tuning range class-C VCO is designed in a 0.18 μm CMOS technology. It achieves a -125.3 dBc/Hz phase noise at 1 MHz offset from a 2.2 GHz carrier frequency while covering a wide tuning range from 1.82 to 2.65 GHz and consuming 3.5 mW power from a single 0.9 V power supply.
