Divide-by-three frequency dividers, based on a parallel injection, are analyzed and the actual locking phenomenon underlying their operation is shown. Analytical results allow us to predict the output steady-states and the locking range in terms of the circuit parameters, thus obtaining useful design insights. The derived results are shown to be very close to SPICE simulation results for a 0.13μm...
We present a nonlinear analysis of differential LC injection-locked frequency dividers (ILFDs) operating at high-level injection regime. We derive the general second-order equation which describes their behaviour and its approximate solution in explicit form, by solving the shortened equations for the amplitude and phase of the synchronized oscillation. These equations are obtained by the classical...
We present a nonlinear approach based on the perturbation theory to analyze the synchronized oscillations in circuits made up of two coupled LC differential oscillators (LC-VCO), widely used in RF systems to generate quadrature oscillations. Closed-form expressions are derived to predict the amplitude and phase of oscillations and their orbital stability. The capabilities of the method are also briefly...
