Abstract
A 1.5GHz CMOS differential VCO reduces the spectral density of up-converted flicker noise by 20dB, thereby reaching the phase noise target of -105dBc/Hz at 50kHz offset required for the PDC receive VCO. Flicker noise is suppressed by this amount across almost the entire tuning range from 1.43 to 1.64GHz, while drawing 6mA from a 2.7V supply.
