description In general, in one aspect, the disclosure describes a simulator for emulating various types of device noise in time-domain circuit simulations. The simulator is capable of adding noise to transistors as well as passive elements like resistors. The simulator utilizes at least one current source in parallel to a device to emulate the noise. The current source generates a random current output to emulate the device noise based on a random Gaussian number and the standard deviation of the device noise. The noise standard deviation can be determined based on the noise power spectral density of the device having a particular bias at that simulation time and the update time. The simulator is capable of emulating any noise source with a constant or monotonically decreasing noise spectrum (e.g., thermal noise, flicker noise) by utilizing multiple current sources having different update steps. The simulator is compatible with standard circuit simulators.
