  An interleaving technique is proposed to enhance the throughput of
current-mode CMOS discrete time chaotic sources based on the iteration of
unidimensional maps. A discussion of the reasons and the advantages offered by
the approach is provided, together with analytical results about the
conservation of some major statistical features. As an example, application to
an FM-DCSK communication system is proposed. To conclude, a sample circuit
capable of 20 Msample/s is presented.
