Abstract

In this paper, a low-power CMOS LC voltage-controlled oscillator (VCO) with body-biasing and low-phase noise with Q-enhancement techniques is presented. A self-body biased circuit is introduced that can reduce power consumption. Some derivations of the Q-enhancement and how to improve the phase noise of the circuit are also discussed. This chip is implemented by the Taiwan Semiconductor Manufacture Company 0.18 µm 1P6M process. The measurement results exhibit a tuning range of 14.7% from 4.92 to 5.7 GHz at a supply voltage of 1.4 V. The power consumption of the core circuit and figure of merit are 2.5 mW and −188.6 dBc/Hz. The phase noise is −118 dBc/Hz@1 MHz at an operation frequency of 4.94 GHz.
