Abstract :
This paper begins with a review of methods for simulating noise in nonlinear analog circuits. These methods tend to be limited to cases involving a single sinusoidal large signal. We investigate two methods that can be used to solve the problem of noise in the time domain also in the case where a large signal causing nonlinearity may contain modulation. In addition, we also discuss a method for calculating the noise power spectral density over a longer period
