ABSTRACT This paper presents a low power 10 GHz voltage-controlled oscillator (VCO) with current reused topology and uses negative resistance enhancement technique. The proposed VCO operates from 9.08 GHz to 10.67 GHz with a tuning range of 16.1%. The VCO has a phase noise of -106.19 dBc/Hz at 1 MHz offset from 10.19 GHz oscillation frequency with 3 mW core power dissipation and 16.27 mW total power dissipation draw from a 1.5 V power supply. This VCO was made by TSMC 0.18 ¿m 1P6M CMOS standard process and the chip area is 0.505 × 0.573 (mm2).
