Abstract
RC oscillators are known for their high phase noise compared with LC oscillators. However, by increasing coupling in RC oscillators one can obtain a quadrature oscillator with noise performance and quadrature error comparable with that of LC coupled oscillators. Measurements were performed on 5 GHz LC and RC quadrature oscillators built in 0.18 mum technology.
