Abstract :
A simple switched-capacitor circuit that generates 1/f δ noise is presented. The circuit realizes a discrete nonlinear one-dimensional map, that generates intermittent chaos with the 1/fδ power spectrum. An integrated circuit with a couple of logarithmic and antilogarithmic amplifiers is used to realize a nonlinear term xZ in the map, which plays a key role in generating 1/fδ noise
