generating a noise current for the associated element,
representing a white noise that exists within the element. The
generated noise current for each noise source is summed with the
deterministic current value for each element and the matrix of
elements is solved after performing all of the summing
operations.
Representative independent claim 1 is reproduced as follows:
1. A simulator for simulating the noise response of an
electrical circuit in the time domain, which simulator operates
in discrete time steps Ts, comprising:
a matrix of electrical circuit elements representing the
electrical circuit;
an analyzer for analyzing the transient response of the
circuit elements in the matrix in the time domain with a known
input signal to provide a deterministic current value for each of
said elements operating in the electrical circuit;
a stochastic noise source associated with each of said
elements, each for generating a noise current for the associated
element that represents a stochastic random process comprised of
a white noise source scaled by the standard deviation of the
physical noise process that exists within said associated
element;
a primary summing device is associated with each of said
elements for summing the generated noise current for the
associated one of said stochastic noise sources with the
deterministic current values associated with each of said
elements; and
a matrix solver for solving the matrix after said summing
device has performed the associated summing operation.
