Abstract :
A dual-band voltage-controlled oscillator (VCO) with switched resonator is described. The dual-band VCO operated near 2.4 GHz and 5.0 GHz with a phase noise of -109.4 and -100.8 dBc/Hz at a 1 MHz offset, respectively. The output powers of the VCO are 3.07 dBm at 2.56 GHz and 1.54 dBm at 5.02 GHz from a 1.0 V power supply, while the total die size was 2.12 mm2, which was achieved by using switch resonator to give good dual-band operation and performance. The power consumption was 26.8 mW for 2.4/5 GHz operations. The rf-to-dc efficiency of the 2.4 GHz and 5 GHz are 7.26% and 5.32%, respectively.
