- In this article, we presents a fully differential 23-GHz capacitively emitter-degeneration double cross-coupled LC-tank VCO. The proposed capacitive-degeneration negative-resistance cell has higher ftrans and lower input capacitance than conventional cross-coupled pairs at millimeter-wave band. The proposed capacitive-degeneration LC VCO shows low phase noise of-105 dBc/Hz at 100 kHz offset from 23 GHz carrier and wide tuning range of 20.8-24.2 GHz, and consumes 10 mA current. The proposed 23 GHz LC VCO shows a good FOM of - 199 dBc/Hz. © 2008 Wiley Periodicals, Inc.
