Abstract

This paper presents a CMOS LC oscillators based on this high-Q active inductor, a negative resistance LC-tuned oscillator with low-constant-power consumption and wide tuning-range can be achieved with low phase noise, wide tuning range, and quality factor in 0.13μm CMOS technology. The active inductor with one feedback resistor results in a gain-boosting factor to improve the Q-value and the inductance (L) of the active inductor. The designed Voltage Controller Oscillator (VCO) demonstrates an oscillation frequency range from 3.268GHz and 4.76GHz, Q-value of 1.975E4, a phase noise of -100dBc at 4-MHz offset, phase noise deviation is less than -247.946dbc/Hz and output power of 12.6531mW with a dc power consumtion of 0.4418mW.
