  • Abstract
    This paper presents transformer-coupled VCO using symmetric transformer. By adopting cross-coupled transistors at both side of transformer, phase noise performance is improved by 6 dB compared with conventional VCO. The proposed VCO has been fabricated in CMOS 0.13..m technology. Measured results show -108 dBc/Hz phase noise at 1 MHz offset and frequency range 6.54~6.86 GHz while dissipating 2.1 mA from a 0.6 V supply.
