General approaches to the problem of generating random Gaussian signals are considered, a variant of practical implementation of such a generator is proposed, some technological aspects of the formation of active device structures are discussed, and spectral characteristics of the output noise signal are presented. The technical solution is based upon the principle of additive formation of a Gaussian process as a result of the joint operation of a group of parallel connected pulsed signal sources of the microplasma type. The proposed devices were implemented as GaAs microchips with
p-n
structures fabricated by epitaxial-diffusion technology, on which a matrix relief of elementary noise sources was formed using the microlithography techniques.
