Abstract
A 1.8GHz LC VCO designed in a 0.18 μm CMOS process achieves a very wide tuning range of 73% and measured phase noise of -123.5dBc/Hz at a 600kHz offset from a 1.8GHz carrier while drawing 3.2mA from a 1.5V supply. A novel amplitude calibration technique used to stabilize performance across the wide band of operation does not degrade the VCO phase noise and consumes negligible power and area.
