Abstract :
We describe a new approach to fully integrated CMOS LC-oscillators with very large tuning range. An experimental oscillator is tunable from 1.34 GHz to 2.14 GHz. The standard deviation of the oscillation period due to thermal device noise is below 250 ppm. Potential applications include wideband RF systems and clock generation in microprocessors
