TLDR
In this paper, the authors present a method for analyzing small signal response and noise in nonlinear circuits, which includes receiving a circuit description and circuit element models, generating circuit equations using the description and models, and determining a periodic stead-state response of the electrical circuit in the time domain.Abstract:
The present invention relates generally to analyzing small signal response and noise in nonlinear circuits. One embodiment relates to a computer implemented method for analyzing an electrical circuit. The method includes receiving a circuit description and circuit element models, generating circuit equations using the circuit description and models, and determining a periodic stead-state response of the electrical circuit in the time domain. The method further includes linearizing the circuit element models about the steady-state response, generating a time-varying linear system of equations, and representing a small signal solution to the time-varying linear system of equations in response to a sine wave input as an amplitude modulated sine wave. The method also includes discretizing the time-varying linear system of equations by discretizing only the amplitude modulation of the small signal solution and performing a time-varying small signal analysis of the electrical circuit using the discretized equations.read more
