Note that the bias sources should be included in the dc term. 33). The total number of equations is 2N + 1, as each harmonic function Hk has real and imaginary parts, except the one corresponding to dc, given by Ho , which is real valued. 33) constitutes the harmonic balance formulation of the oscillator circuit, containing a single nonlinearity of current type only.
The second equation, Im[YT ] = 0, implies the existence of a resonance at the oscillation frequency. The next objective is to obtain the nonlinear admittance function YN (V , ω), which constitutes the model of the active element in the approximate oscillator analysis. The model is based on use of the describing function. For a sinusoidal describing function [16], the input signal is represented by a sinusoid. Considering the nonlinearity i(t) = i(v(t)), the describing function will provide an admittance model YN (V ), depending on the voltage amplitude V .
This will show how the previous analysis at the fundamental frequency generalizes to N harmonic terms. The objective of introducing this formulation here is to provide the necessary background for the phase noise analysis in Chapter 2 and the analysis of frequency dividers in Chapter 4. 1 SteadyState Formulation For the frequencydomain analysis of a given nonlinear circuit, the circuit variables are represented in a Fourier series. For simplicity, a single state variable v(t) and a single nonlinearity of current type i(v) are considered.
