A proposed methodology and integrated circuit for producing signals with 1/f or Lorentzian or white fluctuation noise

Abstract

This paper presents a method to obtain signals with constant (white noise) or Lorentzian type (GR) or 1/f type power spectral density (PSD). The major advantage resides on using the same principle to generate the three types of signals and consequently on using a single circuit. This method can be used to simulate the noise sources inside a device.
