This paper proposes an improvement to the well-known oscillator nonlinear phase macromodel based on Floquet theory. A smoothed form of the nonlinear phase macromodel is derived by eliminating highly oscillatory terms in the macromodel, resulting in a significant speed-up in transient simulation. For an LC oscillator under sinusoidal excitation the new(More)
A new method for computation of timing jitter in a PLL is proposed. The computational method is based on the representation of the circuit as a linear time-varying system with modulated stationary noise models, spectral decomposition of stochastic process and decomposition of noise into orthogonal components i. e. phase and amplitude noise. The method is(More)
A new approach to analyze injection locking mode of oscillators under small external excitation is proposed. The proposed approach exploits existence conditions of the solution of HB linear system with degenerate matrix. The method allows one to obtain the locking range for an arbitrary oscillator circuit with an arbitrary periodic injection waveform. The(More)
A new numerical technique for periodic small signal analysis based on harmonic balance method is proposed. Special-purpose numerical procedures based on Krylov subspace methods are developed that reduce the computational efforts of solving linear problems under frequency sweeping. Examples are given to show the efficiency of the new algorithm for computing(More)
