Optimization of Tunable Oscillators with AM to FM Conversion for Near-Carrier Phase Noise

Overview Nonlinearity in the resonating tank of an oscillator results in conversion of amplitude fluctuations into frequency fluctuations. The effect of this AM to FM (AM2FM) transformation on phase noise is especially important in high-Q oscillators with a wide tuning range.

We develop quantitative time-variant model of near-carrier phase noise incorporating AM2FMconversion, which is both mathematically rigorous and intuitive, and propose new techniques to reduce AM2FM-induced noise in tunable oscillators.

This paper also helps to develop intiutive understanding of its origins and discusses new techniques to reduce it. In section 2, the general formalism is briefly described. In section 3, we illustrate its applications to oscillators with fixed coefficient of AM2FMconversion. Section 4 is about ways to calculate and reduce AM2FM conversion.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?
