In this work we present a new method to lower the phase noise in acoustic resonator based oscillators. This method uses the nonlinear dynamics of a parametric divider made to work close to the bifurcation region. We call this technique "parametric filtering". This approach was applied to an oscillator based on an aluminum nitride contour-mode resonator… CONTINUE READING
