Thanks to the CMOS technology an impressive miniaturization of the electronic active elements has been made possible, which allows for low cost and mass production of complex circuits on a single chip. The natural candidates for very large-scale integration (VLSI) technologies are digital circuits since these can be relatively easily scaled down with large improvements in the operating speed. On the other hand virtually all natural signals are of analog nature, requiring dedicated circuits converting these signals in the digital form, in order to process them with the digital circuitry.
