✦ Synopsis

A balanced voltage-controlled oscillator (VCO) is designed and implemented in a 0.13 lm CMOS 1P8M 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 À108.69 dBc/Hz at 1 MHz offset frequency from the carrier frequency of 17.72 GHz, and the figure of merit is À186.84 dBc/Hz. The core power consumption is 4.2 mW. Tuning range is about 3.
