摘要：

A fully integrated 1 V, 4.4 GHz Inductor-Capacitor (LC) voltage control oscillator is designed for low-voltage high-frequency circuits and used in 5 GHz wireless LAN front-end system applications. An LC tank load is used in the oscillator design to decrease the power consumption. The measurement results show a tuning range from 3.903 GHz to 4.42 GHz for V-tf varying from 0 V to I V. The phase noise is -95 dB/Hz at 100 KHz. The bias voltage inside the chip has an additional capacitor to provide steady power and decrease the power noise injected into the output resonant signal. This oscillator is implemented using the TSMC 0.35 mum one-poly-four-metal 3.3 V logic process. The total chip area is -1.235 x 0.902 mm(2).
