  • Abstract
    An automatic amplitude control circuit to minimize the phase noise of a LC-VCO is proposed and implemented by a 0.18-μm CMOS process. The phase noise lower than -90dBc/Hz at 100kHz offset is achieved over a wide tuning range (from 2.2GHz to 2.8GHz) under large process (ΔVth = ±100mV), temperature (from ∼35°C to 85°C), and power supply (from 1.8V to 3V) variations.
