摘要：
This paper presents a new differentially tuned LC-VCO using a modified anti-parallel. The proposed LC-VCO has lower phase noise and better robustness to the common-triode noise than the previous differentially tuned LC-VCO using the anti-parallel structure. The proposed LC-VCO is implemented using SiGe BiCMOS process. It is tunable from 4.25 to 4.43GHz and the measured phase noise is -103dBc/Hz at 100kHz offset -119dBc/Hz at 1MHz offset over the entire tuning and range. Also, its CMRR characteristic is improved about 2dB. Its core current is 1.7mA at 2.5V supply voltage.
