“…The harmonic balance formulation is better suited to RFIC noise analysis than is discrete time-domain formulation [4], [6], [8], [9], [18], since a frequency-domain formulation accurately handles multitone large-signals as well all arbitrary frequency-defined characteristics which are common case in RF applications.…”

“…Hence, the necessity for computationally effective noise algorithms to keep pace with the increasing circuit size and signal complexity. Numerical techniques for noise calculations in nonlinear integrated circuits under periodic and quasi-periodic large-signal excitations received a fairly extensive treatment in the 1990s from a number of authors [3]- [8]. However, these were mostly concerned with small and moderate size microwave circuits.…”

“…Derivation of transfer function is itself a multiple steps process as follows-first, solve for the (quasi) periodic noiseless equilibrium of the circuit-second, linearize the system equation around the noiseless equilibrium to get the perturbation equation-third, solve the perturbation equation. The solution of the perturbation equation can be performed either in the frequency-domain which results in harmonic-balance based noise analysis [3], [5], [10] or in finite-difference time-domain which results in time-shooting based noise analysis [4], [6], [8], [9], [18]. When dealing with large circuit size analysis, derivation of the transfer function is a numerically critical point to address efficiently in terms of arithmetic operations count and memory storage.…”

International audienceThis paper examines the issue of noise analysis in RF integrated circuits (RFICs). The complexity of the RFIC grows constantly, with transistor counts now into the thousands or tens of thousands. Since RFICs are driven by large-signal multitone excitations, the stochastic noise process in these circuits is cyclostationary. This combination of large device count and noise cyclostationarity makes noise analysis in RFICs a time-consuming task. Simulation algorithms that minimize computer memory consumption and computation cost are thus necessary. There is a consensus now that harmonic balance is the most appropriate circuit equation solution method for multitone analysis of RF circuits. The paper thus gives a comprehensive description of a harmonic balance-based algorithm for computing the circuit noise response, showing how it effectively accounts for all types of cyclostationary noise sources supported by modern compact device models. The algorithm has been implemented in a commercial simulator and shows good capabilities for the analysis of full transceiver circuits within reasonable computer memory occupancy and simulation times

“…However, the PLL is the driven circuit. The present approach is based on a numerical technique [10] which provides noise analysis of nonlinear circuits in the time domain. In contrast to the approach presented in [11], no time-consuming convolution-like procedures involving a transfer function are used.…”

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 illustrated by examples of jitter computation in PLLs.Eyt () 2
