摘要：
A 1.57-GHz low-power low-phase-noise quadrature LC-VCO is presented. This paper adopts current source sharing and higher L/C, L/R ratio techniques to achieve power and phase noise optimization. Verified by 0.35-um CMOS process, the VCO features a much lower power consumption of 6.4mW and a low phase noise performance of -140dBc/Hz@3MHz, with a wide tuning range of 14%.
