1/f/sup y/ noise generation through a chaotic nonlinear switched-capacitor circuit

Description

A programmable switched-capacitor circuit for the generation of 1/f/sup y/ noise is reported. The circuit is described by a chaotic first-order piecewise-linear finite-difference equation which yields a hopping transition between regions of chaotic motions and hence produces 1/f/sup y/ noise. Experimental results illustrating the circuit performance are included.
