• series-tuned resonator

A balanced voltage-controlled oscillator (VCO) is designed and implemented in a 0.13 mu m CMOS IP8M process. The designed VCO circuit topology is an all nMOS LC-tank Clapp VCO using a series-tuned resonator. At the supply voltage of 0.5 V, the output phase noise of the VCO is -108.69 dBc/Hz at 1 MHz offset frequency from the carrier frequency of 17.72 GHz, and the figure of merit is -186.84 dBc/Hz. The core power consumption is 4.2 mW. Tuning range is about 3.32 GHz, from 17.55 to 20.87 GHs, while the control voltage was tuned from 0 to 1.3 V.
