Simulating multi-tone free-running oscillators with optimal sweep following

A new method for the simulation of circuits with widely-varying time scales is given. The method makes a splitting of the behaviour of the circuit in a fast-varying and a slowly-varying component. The method is attractive because it can handle frequency modulated (FM) circuits, unlike existing methods. Numerical results are given.

DRK methods for time-domain oscillator simulation

This paper presents a new Runge-Kutta type integration method that is well-suited for time-domain simulation of oscillators. A unique property of the new method is that its damping characteristics can be controlled by a continuous parameter

Time domain analog circuit simulation

Recent developments of new methods for simulating electric circuits are described. Emphasis is put on methods that fit existing datastructures for Backward Differentiation Formulae (BDF) methods. These methods can be modified to apply to hierarchically organized datastructures, which allows for efficient simulation of large designs of circuits in the electronics industry
