A fully integrated 0.18-μm CMOS LC-tank voltage-controlled oscillator (VCO) suitable for low-voltage and low-power S-band wireless applications is proposed in this paper. In order to meet the requirement of low voltage applications, a differential configuration with two cross-coupled pairs by adopting admittance-transforming technique is employed. By using forward-body-biased metal oxide semiconductor field effect transistors, the proposed VCO can operate at 0.4 V supply voltage. Despite the low power supply near threshold voltage, the VCO achieves wide tuning range by using a voltage-boosting circuit and the standard mode PMOS varactors in the proposed oscillator architecture. The simulation results show that the proposed VCO achieves phase noise of -120.1 dBc/Hz at 1 MHz offset and 39.3 % tuning range while consuming only 594 μ W in 0.4 V supply. Figure-of-merit with tuning range of the proposed VCO is ―192.1 dB at 3 GHz.
